I have a s-video capable DVD player to test with and can alternately switch between Y/C ancd CVBS by decoupling the cables. Y/C looks much better. Using the other cable 9-pin to s-video/composite/L/R and using the s-video the television reports Y/C (using -l 2) but the picture is horrible. For example characters within mythtv are not smooth. With composite the picture is as usual.
Also this cable behaves the same with ivtvctl 0 (comp+s-video) television finds CVBS 1 (comp) television is black 2 (s-video) television finds CVBS but picture is horrible As testing continues I more and more get convinced that the problem is buried within the ivtv driver. Especially the -l 1 I can not explain. I hope one of the developers could have a look into it.

As far as my > investigations go it reports CVBS (Composite). Sorry my TV-set report nothing ... I just see some change in the picture when I change the output mode ... I have another input on my TV-set, this input is RGB. TV is black with all the values above but the picture is red with ivtvctl -l 3. On my S-Video input, I can put an analog VCR which can switch from CVBS to Y/C output. I have the same thing as my PVR with "ivtvctl -l 1"/"ivtvctl -l 2". Have you another Y/C output to test your TV ? -- Jacques Facquet _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
