Hi,

I have an HVR 950Q on my Ubuntu 2.6.32 kernel. I have in fact tried
several kernel versions on a couple of different machines with the same
behaviour.

What seems to be happening is that /dev/dvb/adapter0/dvr0 can be opened:

open("/dev/dvb/adapter0/dvr0", O_RDONLY|O_LARGEFILE) = 0

but a read from it never seems to return any data:

read(0,
[ process blocks waiting ]

Nothing abnormal in dmesg:

This device was working just fine until I rebooted the machine it's
usually connected to earlier today. Now I can't seem to get it working
anywhere.

I'm at a loss where to go from here in debugging. Any hints?

Thanx,
b.
