I've been suffering from an extremely irritating problem for a while - within XBMC as soon as I eject the DVD drive (by remote control, by pressing the button on the drive, by the button within XBMC, ...) it opens then immediately closes again. This makes it very hard to get disks in and out, although through practice I have got very quick on the draw. It is doubly odd, as if I boot to runlevel 3 (not 5), then the drive stays open with no problems.

iMon-remote
I use XBMC on my HTPC, and it is great. I'm using a case that has a built in iMon IR receiver and vfd readout, which also lets me turn the system on from off (which isn't common with lots of PC remote controls). XBMC needs to be set up to work with these.

As my HTPC runs on linux (Arch linux to be precise), this first of all means setting up lirc and lcdproc. My case also has a volume knob and some media control buttons on the front that need setting up too. There are plenty of guides out there on how to set these up, so I'm not going to here - I'm just going to give my config files that might be useful for others.
