[pvrusb2] Snapshot 20060329 Report ....SUCCESS...follow up

[Barry Jett]

Mike and all,

I've had a few days to play with the last two snapshots for the 2040:2400 
device. While I am using the 20060329 snapshot all below applies for the 
20060326 snapshot as well.

For clarity, I've summarized the previous exchange :

Xawtv 4.0

- no luck yet, still getting mpeg2 timeout in 3 seconds message. I've got 
some dmesg files
  I'll send in a separate email.

Mplayer /dev/video0

- works great !  The sound problem was as you stated, Mike.  Xawtv was 
muting the audio.
  Software needs a "did_you_completely_read_the_faqs=1" flag

- mplayer provides full support for the filters on live tv, like 
deinterlacing filters. I use
  mplayer -vf pp=lb /dev/video0  and get a pretty darn good picture.  
Control inputs/channels
  through Xawtv brought up alongside, or /sys/class/pvrusb2......


Mythtv-0.19

- total joy !  The previous problem : Been working 7 12's for a month and 
let my
                 zap2it account expire....hence no channels found  (duh).

- pvrusb2 works flawlessly in mythtv ... no problems encountered.


VLC

- I've really learned to love this program.  Seems to work on everything 
and,
  with the wizard, you can have streaming video effortlessly.

- works great with pvrusb2...d/l the latest source and compile with the pvr
  option.


Thanks again for the great work, Mike.
