[mythtvnz] Channel change stability issues with MythTV andVDPAU in NZ

[Ross and Jemima Knudsen]

Hey guys,

Not sure if its related but I'm having some stability issues on my 
system.  I sometimes get "Encountered a problem displaying video" errors 
both when watching recordings and when watching live TV.  I've noticed 
it happens when a recording starts (ie playback of live TV or recording 
exits). 

Channel change can take up to 2 - 5 seconds to change but I thought this 
was normal.  It may be that I need to improve the signal strength.

But my biggest problem now is that the card seems to fall over pretty 
regularly.  This is noted by the fact that the remote stops working 
along with Live TV.  This can happen anywhere between a few seconds 
after start up and hours later.  The syslog begins to fill up with 
entries like:

Jun  8 20:01:26 mythserver kernel: [ 1453.468507] mt2060 I2C read failed
Jun  8 20:01:27 mythserver kernel: [ 1454.616051] mt2060 I2C write 
failed (len=2)
Jun  8 20:01:27 mythserver kernel: [ 1454.616055] mt2060 I2C write 
failed (len=6)
Jun  8 20:01:27 mythserver kernel: [ 1454.616058] mt2060 I2C read failed

 From what I can google it seems like this problem was supposed to have 
been solved by recent driver updates.  Looks like I am using the 
dvb-usb-dib0700-1.20.fw as it is not symlinked to 1.10.

Nvidia 180.60 VDPAU (JYA release repo)
