You're welcome, and there is no shame in lurking, that's how I started too.
I have been meaning to update that wiki page in a while now as the SATA trouble is fixed as expected, and I'm sorry to say but I haven't been able to get MythTV to work at all, (even with an amplified antenna) I get a weak DVB-T signal and MythTV can't seem to cope or maybe I'm doing something horribly wrong. (Although I also tried mythbuntu on another machine just to test). Either way I never got more then sucessfully scanning the channels (on a good day).
But VDR on the other hand does work rather well and as a bonus has less of a problem with the radeon X1250 chipset (ok after a while the gui went black, but have seen other ATI cards do that as well with other parts of the UI). So I have been playing with that more. I hope that if you have this board that you can get DVB so you can use VDR as well.
Still the main problem with MythTV and this board are the drivers. Allthough the ATI drivers seem to be going in the right direction so I wouldn't be surprised if MythTV would start working with the upcoming drivers (I haven't recently tested the latest). And of course there is always the (hopefully temporary) quick fix of chucking a Geforce 6200 card in, they are around $30 I think.
Apart from these problems everything else seems to work just fine UI1, UI2 (medium/masking only, no blending), playing video, the KDE Desktop and all (never got as far as making recordings with MythTV though but I'm pretty sure they'll play) it's just the MythTV frontend that doesn't work (yet) with the current drivers.
So all and all still a bunch of loose ends unfortunately, but at least it keeps me off the streets.
