|First off, is there a mailing list archive where I can search for this stuff |before mailing the list? I checked the fxtv home page and the README and |didn't see a reference. The multimedia archives are searchable at http://www.freebsd.org/search.html. |Anyhow, I have a second development machine at home that I now have up and |running FreeBSD with a Hauppauge WinTV stereo card. This particular machine |has a Diamond Viper V330 (8MB) in it, which is based on the Riva 128ZX chip. |I have noticed that as soon as fxtv switches into MIT-SHM mode, video just |stops. If the window is obscured, the video just goes black and doesn't |come back until it is fully unobscured. Ok. So direct video works, SHM XImages don't. |Is there a bug in XFree86 3.3.3 that prevents MIT-SHM from working on this |chip? It's remotely possible, but my bets are on the driver not delivering frame-done interrupts to the application. |Is there a way I can fall back to XImages? Sure, several ways. Assuming your routing table is set up standard such that 127.0.0.1 is your loopback (lo0) interface, just do this: setenv DISPLAY 127.0.0.1:0 fxtv Fxtv doesn't go probing the network interfaces of a machine to determine what IPs are local, so if your $DISPLAY doesn't match ":*" or "unix:*", then it assumes you're remote (i.e. no DGA and no SHM XImage transfers will be attempted). I'm gonna bet you still see black when the window is partially occluded, though you're now using standard XImages). If so, please post the output of "fxtv -debug startup" along with your hardware config (card, MSWin* device manager details, etc.) so Roger or another driver expert can help you nail this one down.
