Much obliged. I'll check them out.
I do think there is something with bootup because I have to modprobe to
get cx88 successfully loaded. But, it IS loaded and I can use mplayer to
view HD channels. And, when going into Mythtv, PVR250 works. That's why
I thought it was a configuration problem inside Mythtv, not a driver issue.
