    What issue? The ripple voltage? 400mV isn't great, but it was completely unloaded - with an RPi connected as a load, it would probably smooth that out a lot... Hard to say if the temperature is an issue under normal conditions...

    Did you not watch the video? It appears that when you draw more than ~200ma from the USB Ports they shut down.

    Seems to be related to the ripple but that itself isn't the problem.

    There is a large thread on the official forum about it too.

    Mine arrived yesterday, haven't had a chance to install/test it. Hopefully today.

    So after moving house, I finally got around to setting up my raspberry pi 3 b+ again, but the bastard wont boot. solid red led, no green. reformatted microSD card and reinstalled raspian, still wont boot. tried another sd card, still dead. Measured the 3.3voltage pin, only outputting 2 volts.

    I hope its the power supply and not the Pi itself thats the problem. often got undervolt warnings when it was working at the old house.

    Going to pick up another power supply tomorrow and retest it. I hope its not the Pi. :mad:

    HI guys

    I am looking to purchase one of these (Pi3) units to use as a low powered HTPC, are they still the (bad vision and 100 pages is too much) go for this. I will buy an all-in-one (linux) kit to save time, is Kodi still good for controlling mostl content. I don't have alot of stuff but if and when I do, I aim to connect it via (off the shelf?) NAS to save from swaping drives :(

    I believe there was a link her somewhere about an offical site to puchase, is there anything firmware or software wise I should look out for to get or to avoid issue, etc?

    Edit
    Just read this, what's the issue?

    Thank you!

    I went with a 4gb Rock64 for the media centre. I haven't set it up yet but it should go great guns. The Raspberry worked but was too laggy. Plus the Rock64 has 1xUSB3 and 2xUSB2, where as the Raspberry pi only has 1 USB otg (in terms of bandwidth, it uses a hub for 4 ports)

    I still use a Pi as my HTPC.
    It does everything I want it to do, although, all I do is play content (mostly 720p, some 1080p) across the network.

    I use the OSMC image.
    It includes Kodi set up and ready to use, you just dump the image on the SD Card and boot it. It also supports booting from USB if that's something you want to do.

    The issue I am referring to is the POE Hat not working correctly. Seems to have problems with USB power draw. I just bought one without knowing.

    The RPi works up to 1080p H.264. If you're getting lag, it means you're probably watching H.265 media, or you need to update whatever software you're using.

    If you want fall-off-a-log easy, I recommend LibreElec:
    https://libreelec.tv/

    It'll connect to any standard SMB or NFS NAS. An RPi3 over WiFi is plenty fast enough even for 1080p H.264 content - certainly no need for faster connectivity than that.

    But again, if you're using mostly H.265 content, the RPi has no hardware support for that. Some other devices like the OrangePi, ODroid, etc do in their higher models, but software support can sometimes be less straight forward.

    I used LibreElec, video playback was (mostly) fine. The "lag" was noticeable when navigating around the interface. scrolling through lists of media was particularly painful.

    I'm still running an RPi2 with a very vanilla LibreElec setup and LOTS of media, zero problems with lag.

    How are you navigating? I notice my remote control via HDMI-CEC isn't the speediest (even on my name brand Sony Bravia TV). Although interestingly enough it's still faster than Netflix on my FetchTV box, so go figure.

    But if I use the "Kore" app (a glorified telnet to Kodi's in built listener on TCP8080 wrapper), navigation is lightning fast. Ditto for the built in web portal that does the same thing.

    https://kodi.wiki/view/Kore
    https://play.google.com/store/apps/details?id=org.xbmc.kore

    Navigating deep trees of media, navigating within media itself (dragging the position bar to jump ahead or behind), etc is all super speedy via that. Says to me that CEC is the lag factor, and not the RPi itself?

    +1 LibreElec except I use OpenELec on a N2820 NUC and use a old tablet as a remote, is good for all media up to and including 1080p as long as it is H.264 (as elvis mentioned above).

    I'm now looking at something a bit more powerful to drive 2160p H.265 as the N2820 integrated graphics lags out, and seriously considering a Pine / Rock64, would be interested in the results you got rockofclay.

    That's the issue I'm having with my T.V which I just released, I do make an effort to d/l 720p but when in a hurry ...well, you know :(

    I have a 4 year old 40" Kogan television with usb and hdmi support but the ports and/or firmware are (no interest connectors to update) old ...so, I get a new T.V /w net support or get a media device ...looking for the cheapish way out, thoughts?

    thanks guys

    I don't really understand your post.

    Are you saying you currently have trouble with 1080p media? or your current solution only plays up to 1080p?

    I have no problem playing 1080p content on my Pi, however, anything higher (H.265/2160p) and you will have problems as they are not made to play it.

    Sorry for the confusion, I can't play above 720p but I would also like to purchase/build a cheap media solution for doing so and prefer the abilty of playing most formats?

    If you want a device that plays media directly:
    * RPi if you know you'll be playing a maximum of H.264/1080p (the codec matters as much as the resolution)
    * ODroid, OrangePi, and others if you want H.254/HEVC/4K (again, the codec matters there - an RPi won't play H.265/HEVC at 1080p either)

    If you want to stream from something else, get a ChromeCast.

    I use both for different reasons. ChromeCast is excellent for support streaming services - Netflix, Stan, Spotify, Twitch, YouTube, etc. But Kodi is much better for media you have sitting on a network-attached-disk somewhere.

    My brand new Sony Bravia runs a full Android stack, and so it runs Kodi natively with H.265 support courtesy of whatever processor is inside the TV, and also offers full ChromeCast functionality. That's freed up one of my RPis for me to do something else with. At this stage, likely some sort of emulation project - considering turning a little kiddies driving toy into a mini driving cabinet like this guy did:

    Cool, am much clearer now, will most likely go with both as that is what I aim to do ...may get a better/faster t.v later to support it all?

    Thank you, all!

    Navigation is done using a Media Center clone remote and USB IR receiver.

    I like the tactile feedback of actual remotes. I've got Yatse and Unified Remote on my Phone, but don't tend to have that near me when I'm watching TV, and wasn't a fan of using them for every-day navigation.

    That's fine, but from a pure troubleshooting point of view, what's the response time between something like Kore and your physical remote? Worth testing at least to see if it's the Pi or the type of controller that's at fault.

    I gave up on USB remotes some time ago, because I found them universally terrible. Hand on heart, I only bought cheap and nasty ones. So that could entirely be my fault.

    Not necessary if you're sticking to external devices. They all just send a HDMI picture to your telly, which is all very basic, standard stuff for any TV with matching input to decode.

    I'd have to check next time I'm playing with one, I went down the NUC route for my HTPC and it hasn't missed a beat. the Pi's were re-purposed as a Kids Internet/Scratch Machine, and as a Home Assistant box
