What hardware revision is your HVR-950Q ?
(the sticker on it should say, as will the tveeprom logs in syslog).

I have revision B3F0 versions here which work very well for ATSC (no cable here).
But the newer B4F0 versions appear to expose a race condition between
the various kernel modules which drive portions of the device.

The B4F0 ones (in most but not all systems here) don't work after
initial bootup.  They can be made to work though, by stopping mythbackend,
unplugging and then replugging the device, and then restarting mythbackend.

Does any of that help you there?
