Hans, I am having problems with sound and picture quality on some channels with my PVR-150 (as described in http://www.ivtvdriver.org/pipermail/ivtv-users/2005-October/000159.html). I tried using "ivtvctl -g reg=0x808,val=0x1f" and it changed from no sound to white noise on one of the affected channels (and the channel stayed b/w, but I am not surprised at that!). Here's the tveeprom output if its any help. tveeprom: ivtv version tveeprom: Hauppauge: model = 26582, rev = C299, serial# = 8440358 tveeprom: tuner = TCL 2002N 5H (idx = 99, type = 50) tveeprom: tuner fmt = NTSC(M) (eeprom = 0x08, v4l2 = 0x00001000) tveeprom: audio processor = CX25843 (type = 25) tveeprom: decoder processor = CX25843 (type = 1e) Thanks for your time, Doug __________________________________ Yahoo!
