I have a system (Fedora Core II) with a PVR350 and a PVR250. The first tuner works OK, but the second does not. Here are the relevant logs and config info:
When trying to enable PIP, the menu freezes on the screen and I get this in mythbackend.log: Error setting format VIDIOC_S_FMT:: Device or resource busy >From then on I can no longer exit live TV, change channels, or get the menu to respond.
