Some update, encountered today: My PVR-150 card will not change channels after dist-upgrading dapper kernel 2.6.15-22-k7 to 2.6.15-23-k7. After a while the frontend it willl display some error like 'could not receive blah for 15 seconds'... SOLUTION: While going back to -386 kernel, the problem is fixed again. -- Hendrik van den Boogaard
