As another data point - I have two HD-PVRs and two backends - one is rock
solid, the other one is super flaky. Here's the kicker though, it appears
that the issue is more with the backend hardware than with the HD-PVR.
If I swap which machine each HD-PVR is hooked up to, the same backend is
still rock-solid and the other one is still flaky. The stable one is an
older AMD box, and the unstable one is a newer Intel box. They're running
basically the same custom kernel (with a few different drivers for HD
controllers etc)
The conclusion that I'd come to is that the Intel chipset's USB drivers
weren't playing nicely with the HD-PVR, but I haven't had a chance to do
more digging on it beyond that.
