I already went through the effort of making a VGA->SCART converter cable (I can provide schematics and photo's if you'd like) hoping that it would bring me the ultimate in MythTV viewing. But it didn't.
It gives the best colors (separate R/G/B and sync) and sharpness of all possible methods, but... no smooth motion - on my setup that is. Some of you may recall my postings about struggling to get either bobdeint working on my SiS video (ASUS Pundit) or completely bypass the TV-out that can't handle interlaced video properly.
When I finally got the modeline right for the VGA-SCART cable to work I was hoping that the video encoded by my PVR-250 (interlaced material) would play back 1:1 on the TV. Somehow, it gave the same blurry motion that kerneldeint or linear blend, or even 'no deinterlacing' produces, not 50 fields/sec but 25 frames/sec. Not even close to the perfect display you get using bobdeint. As an extra, the ultra sharp picture really made the MPEG artifacts clearly visible which isn't a pretty sight too, not to mention not being able to monitor the boot procedure because of the garbled image.
So the cable wasn't really that hard to make and it only cost me € 5,- but I found the results rather unsatisfying. See also an earlier post from me on this: http://www.mail-archive.com/mythtv-dev@mythtv.org/msg03975.html
I gave up after trying *every* combination of driver/cable/modeline/X11 video output device/eating shoes and decided to buy a nVidia card after Staffan Pettersson persuaded me (thank you): http://www.mail-archive.com/mythtv-dev@mythtv.org/msg04131.html
The card is due to arrive friday, so I can finally get OpenGL vsync+XvMC+bobdeint working.
And what about YUV *Progressive* input - is there a way to get it out of VGA connector in the similar way how TV out of VGA was made? My TV supports this and since it is Progressive (my TV is 100Hz tube), I suppose it will solve most of problems with interlacing/deinterlacing.
Does anybody know the details of YUV Progressive format?
