After upgrading to a clean 7.3 I have lost my TV screen. Right now it gives only a black screen and nothing more. I have not changed anything in thesettings for my Hauppage (old) card. After running xawtv in a console window I get following info: ' ioctl: VIDIONSYNC (0) Input.output error." Could somebody tell me what that means? And what I should to to get my TV screen back to business?
