Sorry I didn't reply to this right away.  I saw the last paragraph and 
had interpreted it to mean that you were done, but I should still try to 
answer these questions.  I saw this again while cleaning out old e-mail. 
  So for what it's worth...

You will get a zero length file if encoding simply didn't start. 
Looking in your kernel message log at that point might shed more 
information on this.  Maybe.  You likely won't get a stream if the 
device failed to tune the right channel (no video lock can mean no data).

No, it isn't possible for the cable distributor to specifically prevent 
your use of the PVR device.  If you can record the channel with a VCR 
then you should be able to capture it with your pvrusb2-driven tuner.

File system type should not matter at all.  The /dev area is normally a 
different mount point anyway (in debian it's tmpfs, managed by udev). 
Your target (test.mpeg) of course is sitting in ext3 (or ext4), but 
really if you can't cat something into a file then there are bigger 
problems afoot than the pvrusb2 driver :-)

I might have asked this before, but are you sure you are tuning the 
right frequency?  With the cat command you tried it's just going to tune 
to whatever the last frequency was that you set (usually I use the sysfs 
interface to set that frequency).  Can you get it to work using the 
composite input feeding from a VCR or DVD player?  If so, then pretty 
much everything is working and the only question left is the RF tuner 
(e.g. is it on the right frequency, is the RF tuner's driver working 
correctly, etc).

Any progress with those?
