(II) intel(0): Mode for pipe A: (II) intel(0): Modeline "NTSC 480i"x0.0 107.52 1280 1368 1496 1712 1024 1027 1034 1104 (62.8 kHz) This is the mode only used in load detect, so you can ignore it. Could you attach X log? and what's your environment? using kms or not? I have no idea where those 480i/60 came from. You should only see mode name like "1024x768", "800x600", etc. in xrandr.

The Xorg logfile
Not using kms (tried it, does not seem to go well with TV at all, but that is a later bug).

output from xrandr --verbose
As you can see the modes you talked about is there, but also a list of other modes as you can see.
I cannot choose them with xrandr ("xrandr: cannot find mode 480p/60"). But as I see it: if I should have native TV-modes there, then it is not the ones for NTSC I should have.
I don't understand where does those "480i/60" modes come from, as intel TV will only add modes for current TV_FORMAT from following table:
{"640x480", 640, 480},
{"800x600", 800, 600},
{"848x480", 848, 480},
{"1024x768", 1024, 768},
{"1280x720", 1280, 720},
{"1280x1024", 1280, 1024},
{"1920x1080", 1920, 1080},
That's the only modes we can support for TV. Do you have some script to add those modes by yourself?
Just don't use them. ;)
Actually to use 480i or other HD formats, you should have 9-pin S-Video and a S-video to component converter, then use our new option "TV_Connector" to set 'component' type, Then you can use HD formats through TV_FORMAT property.
Oooops. After another go it seems like those modes where actually added by my MC-software, set to start by default. ok, close this. |

Using server version 1.6 and driver 2.6.99.902 if I in xorg.conf set TV_FORMAT PAL the output of xrandr --verbose will change its output to TV_FORMAT: PAL However it only presents me with NTSC-modes, 480i/60 (0xa4) 12.0MHz h: width 640 start 664 end 736 total 760 skew 0 clock 15.8KHz v: height 480 start 484 end 492 total 525 clock 30.0Hz 480p/60 (0xa5) 23.9MHz h: width 640 start 664 end 736 total 760 skew 0 clock 31.5KHz v: height 480 start 484 end 492 total 525 clock 60.0Hz and looking in Xorg.log I cannot find any references to pal, but I can find this: (II) intel(0): Mode for pipe A: (II) intel(0): Modeline "NTSC 480i"x0.0 107.52 1280 1368 1496 1712 1024 1027 1034 1104 (62.8 kHz) (II) intel(0): Adjusted mode for pipe A: (II) intel(0): Modeline "NTSC 480i"x0.0 108.00 1280 1368 1496 1712 1024 1027 1034 1104 (63.1 kHz) (II) intel(0): chosen: dotclock 108000 vco 2160000 ((m 90, m1 14, m2 8), n 2, (p 20, p1 2, p2 10)) (II) intel(0): Detected S-Video TV connection For a PAL the choice should be 576i/50 or 576i50. You may choose the latter, since xrandr does not seem to play well with modes having '/' in their names.
