When you compile mythtv-0.19-pre8624 with the unichrome USE flag, it runs configure with --disable-xvmc and --enable-xvmc-vld. The prior due to the lack of a "nvidia" use flag. Unfortunately, this causes configure to disable all xvmc (including xvmc-vld). INterestingly configure is cablable of auto-detecting (due to the presense of XvMC libraries) whether it should be using XvMC-vld or not. So to fix it I added the two lines: use unichrome && myconf="${myconf} --enable-xvmc" use nvidia && myconf="${myconf} --enable-xvmc" and took out the lines $(use_enable nvidia xvmc) $(use_enable unichrome xvmc-vld) This seems to configure correctly now.

Not having particular experience in ebuilds, I am not sure this is a good fix. Thus I am not going to try and check it in myself. Cheers -Alex
Fixed in mythtv-0.19
