[pvrusb2] New driver snapshot: pvrusb2-mci-20060329

Thu Mar 30 13:01:08 CST 2006

Hi,

Maybe I'm missing something but it seems the last snapshot has introduced some
breakage.
With mplayer it is ok but xawtv does not work anymore.
xawtv -debug = 2 gives this log (I hope this is helpfull):

As a result, xawtv display nothing but this initial starting screen.
I can switch channels. xawtv display the channel name but I get no image and no
sound. Once again, mplayer and sysfs just work :)
