Post subject:  PVR150 slow after upgrading from R5D1 to 5.5

I have a 1200MHz PC with 512M of RAM and a Hauppauge PVR150.

I installed Knoppmyth R5D1 and could watch live TV fine and the recorded programs too. Recently I upgraded to 5.5 and now the video is very slow. So slow and often pixelated that MythTV is basically unusable.

Are there some simple config files I can just RESTORE from the R5D1 backup? If so which files? Otherwise any pointers would be great! I have searched for PVR150 and 5.5 but found nothing useful after many pages.

I've checked the log files for clues per the guide http://www.knoppmythwiki.org/index.php?page=CheckingLogFiles

Only dmesg showed something significant:
Code:
   ivtv0: Cause: the application is not reading fast enough.
   ivtv0: All encoder MPG stream buffers are full.  Dropping data.
      <repeat this 100 times>
   NETDEV WATCHDOG: eth0: transmit timed out


top showed this while I was watching a recorded show:
Code:
   CPU 95.6%us
   Mem: 502M used 8M free
   Swap: 80K used 760M free

   86%   Xorg
   13%   mythfrontend
   .3%   mysqld
   ...


Thanks for Knoppmyth - until now I've had no problem that I couldn't correct using these forums.

FWIW:
dmesg | grep tuner
tveeprom 1-0050: tuner model is TCL 2002N 5H (idx 99, type 50)
