I dont think it has anything to do with MythTV. When using the
2.6.35.11-83.fc14.x86_64
kernel, the following command fails 'mplayer dvb://WUSA-HD'. With the
earlier  2.6.35.10-74.fc14.x86_64 kernel it works fine.

The one difference I see in the logs below is
'pvrusb2: firmware2 upload transfer failure'

If this is abnormal, I wonder what kernel change broke the firmware
downloading?
