[arch-general] MythTV

My previous MythTV box, running opensuse 10.2, just died (HDD failure). Replaced the HDD and installed Arch for n minimal MythTV platform; on an old AMD Athlon 1.2G, 512Meg RAM, NVIDIA FX5200. All installed fine, but I get "Bus error" if I try to run any MythTV app. I guess it was compiled with some Intel only feature? Anyone have some suggestions? or should I just grab a copy of Mythbuntu? Manne
