For the benefit of anyone who might have similar problems. These tricks are mostly already mentioned on the list but others might still find them interesting... I have a Flyvideo3000 with 2.4.20 kernel, v4l patches, saa7134-20030326, xawtv-20030325. After about a week of use the video goes and I get some v4l invalid ioctl messages when ever I change channel. Fixed by cold reboot. On Fixing the above - sound is often not working. Running radio -f <freq> will give me (mono?) sound. I can't change channels because I get a message about invalid frequency (I think it then refuses the request). loading saa7134 always complains the autoscan fails. Some playing around with loading and unloading fixed the problem. In particular I *think* unloading saa7134 and then tuner and then loading first the tuner, waiting and then loading saa7134 avoided the autoscan failure problem and gave me a perfectly working sound/video. e.g. modprobe tuner *wait* modprobe saa7134 card=2 May be a slight bug in the autoscan which blocks tuning if the "autoscan" or what ever fails which is avoided by the above. May be just dumb luck - but I thought it worth mentioning. Andrew
