I'd want something with HDMI out, digital optical audio out and an onboard NVIDIA card supported by VDPAU... what do you use?

Have a look at the ASrock Ion 330 if you wanna buy a new case/psu/board with Atom/Ion. You can get one that comes with a remote. Not sure what type of IR receiver it is.

I second the asrock ion suggestion they rock... err pardon the pun...

To shutdown for suspend you can program your power button to use irexec sudo pm-suspend
or you could get irexec to run a short scripts like this (better than above)

killall mythtv
killall xbmc 
sudo pm-suspend

You must give your user sudo rights with no password for it to work.
To wake from a suspend you need to enable usb power on the usb port your receiver is plugged into using a command like this

sudo sh -c 'echo "USB0" > /proc/acpi/wakeup

'
for it to work everytime you need to add it to your /etc/rc.local file (in ubuntu)
If it doesnt work move the receiver around the usb ports until it does and if that does not fix it then you try USB1 and then USB2 .....
A guide is here... This should work for all remotes not just mce as long as you change things accordingly.

The dvico usb receiver however will not play this game I have found .. You might find joy though!

Wow. Worst advice I have ever seen here.

While having no password for any super user requirement is a bad thing, you can at least limit the damage to specific commands - visudo and add the following line:

youruser ALL=NOPASSWD: /usr/sbin/pm-suspend

where youruser is the username that requires access to the pm-suspend command.

I think thats what he was suggesting.

I don't, but I would be happily be proved wrong

[RILEYP]

I was on my windows pc at the time and so couldnt bring up the exact code I have.... here it is....

dad ALL=NOPASSWD: /usr/sbin/pm-suspend

heres another link to enableling wake up from suspend as well

HP IR from ebay, they're like $20 shipped. Shows up as a Phillips eHome IR Receiver, works perfect with the Hauppage MCE remote or any harmony.

What they said!

Asrock ION 330 (~$300), 2Gb RAM + smallest laptop HDD you can find if don't have them laying about and HP IR previously mentioned. Mine a few months back was just under $500 all up with a MCE remote kit and the RAM/HDD was a bit more expensive so probably under $450 now days.

Shame the Revo R3610's dried up, my last one of them cost me $350 complete with IR!

As for the suspend stuff, I was gonna point you to the XPMCE forums but RILEYP covered it well enough.

[RILEYP]

Dave he is after a remote that uses non ms ir codes so it does not interfere with his xbox 360. The hp receiver you suggest uses ms ir codes. I have one of those ebay hp receivers and use it with a genuine ms remote and it works perfectly though I cannot program the volume buttons to learn the volume buttons of my tv like its supposed to be able to do??? Any ides here?
My remote is a rc6 ir us pat 5.877.702 rrs9002-8601fc and on the inside of battery cover has a small sticker with a number 70129B
Its the black one with the teletext button at the very bottom centre

On the topic of remotes, I am having all sorts of trouble getting my Sony LCD tellys remote codes correct. The codes I generate are recogised by lirc as the Sony remote but the telly does not respond to those codes when I transmit them via a LED.

This setup worked fine with my old toshiba telly so I figure it's just something funky on the Sony telly, any ideas on how I can work around this? I've tried the codes listed on the lirc site too for various remotes until I could no longer take changing the LIRC settings around.

Hmm, I've been looking at the fragmentation of my XFS logical volume:

$ sudo xfs_db -c frag -r /dev/mapper/vg_sata-lv_mythtv_xfs 
actual 123943, ideal 424, fragmentation factor 99.66%

I'm pretty sure that 99.66% is a bad thing I've followed the instructions here:http://www.mythtv.org/wiki/XFS_Filesystem, and here: http://www.mythtv.org/wiki/Optimizin...-Specific_Tips

Has anyone else done some of the stuff here, like noatime, nodiratime?

I was using the Hauppage MCE IR and remote but switched to the HP item with a Harmony One. Also have an Xbox 360 and had no issues with either configuration?

I don't know what impact it has on performance other than I don't notice any issues either with copying over the gig network or recording 3+ streams at once. But if it helps, here are my 2 XFS filesystems.

#/dev/sdd              596G  441G  155G  74% /srv/recorded_tv
LABEL=tv        /srv/recorded_tv        xfs     defaults,noatime,nodiratime,allocsize=512m      0 2
# xfs_db -c frag -r /dev/sdd
actual 769, ideal 276, fragmentation factor 64.11%

#/dev/sda              1.8T  1.5T  265G  86% /srv/storage
LABEL=storage  /srv/storage    xfs    rw,noatime,logbufs=8,logbsize=256k,nobarrier       0 2
# xfs_db -c frag -r /dev/sda
actual 18528, ideal 17210, fragmentation factor 7.11%

Kewl, thanks dave- for the information about your xfs filesystems.

I found that the laptop I was using as my MythTV frontend responded to MCE commands from my Harmony One, but my XBox360 would respond to those same commands as well! I managed to purchase a year of XBox Live gold before figuring it out So I want a receiver which isn't MCE-based.

Maybe you need to reconfigure the activities? My Xbox360 is set to be off when using the activity that controls my HTPC and vise versa. Have never had the wrong unit being powered up or controlled.

You could try the Jaycar fake MCE remote (~$30). It's actually a remote emulating a wireless USB keyboard. You could use the IR on that and program the harmony to send the appropriate commands. Might be a bit of mucking around. Before patching my kernel for IR wake from standby support, I was using it as a 2nd IR and set the harmony to send a command to wake the machine as it was really a keyboard press rather than an IR command needing lirc. Hope that makes sense?

It's not the Harmony which-devices-are-on-at-what-times configuration which caused the problem, I would use the Harmony 'devices' screen and send the 'turn on' signal to my MythTV frontend and both the frontend and the 360 would power on at the same time!

hmm, that's an option alright - I'm going to spend some time looking around to see what else is available. I'm very tempted to just spend ~$6-7 AUD on one of the generic USB remotes available from china on eBay, and gamble on the device being supported in the Linux kernel.

Ah I get ya.

That is why I suggested the Jaycar item, I know it works. But the china items would be the same generic crap. The jaycar one is listed as a holtek hid usb device keyboard and mouse.

Given myth is driven by keyboard commands anyway this won't be a problem. Only thing I can see being a headache is learning each key into the harmony. I never played around with it beyond learning a single keystroke.
