I currently running a HVR-1600 along with a PVR-150 and PVR-500, under
Fedora 17 x86_64

My HVR-1600 does this occasionally also. I some times get a red
recording and sometime a grey recording. Just to complicated matters my
over the air tuner ATSC some times is detected and other times not.

I'm guessing there is some driver issues since I tend to reboot the
computer and some point both the Analog and ATSC devices seem to get
recognized.

I just haven't spent the time so see what is causing this. So I'll have
to keep an eye on this thread.
