Can you post your tveeprom output from the kernel log? I'd like to know which tuner it detects on your card. Only certain NTSC tuners are affected according to the information I received. Hans
The output of tveeprom is as follows: tveeprom: ivtv version tveeprom: Hauppauge: model = 26032, rev = C199, serial# = 7954427 tveeprom: tuner = TCL 2002N 5H (idx = 99, type = 50) tveeprom: tuner fmt = NTSC(M) (eeprom = 0x08, v4l2 = 0x00001000) tveeprom: audio processor = CX25841 (type = 23) tveeprom: decoder processor = CX25841 (type = 1c) Thanks, Shawn _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
