So the video output from the satellite box is a RCA phono connector connected to a little adapter which plugs into the composite / svideo connector on the Hauppauge card? You might try using "setchannel -s" just to see what happens. 2) You might try changing the loop in cxm_saa7115_wait_for_lock from 10 to 20. > When using the -t option: > ioctl( tfd, METEORSINPUT ) failed.: Invalid argument > ioctl( tfd, TVTUNER_SETCHNL ) failed.: Invalid argument > > # dmesg > cxm0: video decoder failed to lock > cxm0: audio decoder failed to lock As a dumb question ... I take it the coax connector on the Hauppauge is connected to the output of the cable box? Using -t to switch to the tuner will "fail" if the tuner isn't set to a valid channel. The input actually does switch ... the METEORSINPUT ioctl merely seems to fail because no valid video signal was detected. The TVTUNER_SETCHNL should not fail if a valid video signal is present at the chosen channel. The BG channel mapping used by the cxm driver maps channel 43 to 647.25 MHz. You mentioned 647 MHz ... did you mean 647.25 MHz? -- John ------------------------------------------------------------------------- | Feith Systems | Voice: 1-215-646-8000 | Email: john@feith.com | | John Wehle | Fax: 1-215-540-5495 | | -------------------------------------------------------------------------
