I have a similar problem. I use a Hauppauge WinTV BT878 PCI on a SuSE 8.2.
Starting LiveTV crashes the backend and in the frontend there only stays a
black screen telling me in the console that it tries to connect to the
backend. But the backend has already crashed with the following messages:
ioctl VIDIOC_G_FMT: Das Argument ist ungültig
mythbackend: ratecontrol.c:362: get_qminmax: Zusicherung »qmin <= qmax« nicht
erfüllt.
Abgebrochen
