Although I didn't find a livecd that works with the TV part of my All-in-wonder, I did find a distro with ATI drivers. PCLinuxOS has three versions of their LiveCD. They have a regular version, an ATI version for Radeon cards and a Nvidia version for geforce cards. Their LiveCD works well on my system with an ASUS A7N8X deluxe and Geforce 6800 GT. The only problem I'm having with PCLinuxOS is sound issues. I'm not getting the LIne-in on sound card features and no sound in Q3A demo. Any who, here's the link to their torrent archive:

this is probably not needed but I'll write it any way
PCLinuxOS-ATI-81a.iso.torrent is for ati cards
PCLinuxOS-NV-81a.iso.torrent is for Nvidia cards
PCLinuxOS-81a.iso.torrent is for all cards, no 3D acceleration
