Hi... I've been trying to test openH323. In a few occasions, when something happened, I loose video completely. After running this program, xawtv doesn't show images anymore - just a black screen. No amount of juggling with parameters produces anything. I even tried to unload and reload the modules that have anything to do with video - all v4l, i2c, modules. After calling xawtv - without success - these are loaded automatically: tuner 8196 1 (autoclean) saa7134 48108 0 (autoclean) video-buf 7984 0 (autoclean) [saa7134] i2c-core 12128 0 (autoclean) [tuner saa7134] v4l1-compat 10260 0 (autoclean) [saa7134] v4l2-common 4088 0 (autoclean) [saa7134 v4l1-compat] videodev 5376 3 (autoclean) [saa7134] No images though. It takes a reboot to wake averything up. Suggestions abt things to test? John
