I'll see > if I can get ahold of a semilar setup somehow... The TV card is a Hauppauge WinTV PCI-FM. Tuner seems to be Philips PAL B/G (I attached the appropriate section of the dmesg.boot below again). I guess that this card is probably not really available anywhere else but in Germany. Probably it is sold in some other European countries as well, but at least (a part of?) the UK seems to use a slighly different form of PAL so that they would at least need to put a different tuner on a UK card. Your 686B fix already solves 95% of this problem, but I still did some more investigations: Under Windows (of course same system, without special VIA fix), the card works properly. The same is true for Linux. That doesn't tell us much, except that there must be some way (whatever it may be) to solve this problem. Probably you will be able to set up a similar system, but I have the strange feeling that it's actually the design of my Chaintech 7AJA/100 board that plays a large role in causing this problem, so without this board, it's well possible that everything works fine. In the end, I guess the question is if we are really about to solve something that affects a lot of FreeBSD users, or if the problem is only there because I bought cheap s*it... ;-) Greetings Nils -- Nils Holland Ti Systems - FreeBSD in Tiddische, Germany http://www.tisys.org * nils@tisys.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
