Movie plays on computer monitor, but not on tv screen

[adamsummers]

I have an Apollo 64MB GeForce2 MX card with S-Video out converted in to composite RCA for my television. When I watch an .avi or .mpg, I can it on both the monitor AND the tv. But when I try to watch a .dat, even converted to .mpg, I can see it on the monitor but NOT on the tv.
How very strange?
I have tried Media Player, Xing and WinDVD with no luck.
Does anyone know how to fix this?
Any replies would be much appreciated.

Whoa, that is peculiar...
That makes me hesitant to upgrade my video card to one w/ TV-out...

This dat file, what is it ?, a NTSC or PAL, diffrent to your TV ?

Your computer will display NTSC or PAL, but your TV wont, is that the problem ? Have you converted the dat file to the correct mpeg type ?

I have the same problem with a Radeon VE with DAT files (NTSC or PAL), mpeg, mpeg2, and wmv. If I find some kinda solution for my card then I will pass it along and it may help you.

Hi everybody
I think I have the same problem:
movie plays on computer monitor, but not on TV screen. (Desktop and everything else is visible on TV, sound is ok)
This is what I tried:
- RealPlayer is the only software which can play the movies, though it does not support too many movie formats.
- I tested about 5 other players (or more, believe me but none of them would display the movie on TV.
- If I switch off the hardware acceleration of my video card (ATI Rage Mobility 128 AGP) all software players display the image on TV, BUT upside-down!
I have come to the conclusion that this is a pure software problem.
Reasons a manyfold and I don't know which is actually true:
- Copyright protection issues (I connect my S-video out directy to the video recorde) (I do not believe in this reason very much)
- Perhaps a video driver (video card specific) problem (the decoders should work fine, since the display works for RealPlayer)

I finally sent some emails to Microsoft and other player software providers, but if I received an answer, it was always answered with the copyright reason.
Please let me know, when (not if) you have solved this problem.
