Please send me an mpeg snippet showing what you have (just e-mail it to 
me directly).

Well that's an improvement but we haven't learned a thing about why it 
was wrong in the first place :-(  And I'd like very much to figure this 
out because probably others will hit this problem (like Vincent).

Did you change kernels?

Unless an application runs and specifically modifies the device 
configuration, the choice of the initial video standard is entirely 
contained within the pvrusb2 driver, based only on the hardware it sees 
and any module options you might have specified (unlikely).  I'd 
*really* like to know why your initial video standard selection has 
magically changed.  Knowing that likely will shed some light on this.

Vincent: Can you follow the steps I outlined in the previous message?
