[pvrusb2] only few informations for udev available

sounds great!

I am currently using a recent v4l-dvb snapshot. I think mixing it with modules 
built against the kernel sources will result in unresolved symbols.
Could you integrate these patch in your hg repository?

I am anxious :-)

I now also have a HVR 1900. You may remember - I asked some time ago the 
possibility for an "analoge-only" mode. Well, that is not necessary. I can 
use the adapter_nr and set this to a high number. vdr counts all found dvb 
devices and stops its search once a number is not used. 
This way I can use the analogue part. I noticed that channel switching is much 
smoother compared to the older PVRUSB2. I takes a litlle bit longer, but it 
blanks out the video and seems to start perfectly with an i-frame.  

I no longer close/re-open the pvrusb2 devices for channel switching. You know, 
I made this to stop and start the encoder, but too often I get encoder stuck 
errors, black screens and freezes. Now I only stop the read thread, tune and 
start the read thread again. There are still a few artefacts visible (encoder 
ist not cleared) and there is a loud audio crack, but this way the PVRUSB2 
works stable.
The HVR 1900 does not have these problems. What is the difference? An other 
digitizer?  

By the way: Is there still analogue cable TV in the USA? Does it have a 
deadline? I remember that I read that at least the analogue terrestrial 
broadcasting ended some months ago.

Greets,
