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?
