TV-out shears?

I've got a Guillemot 3d Prophet FDX 8500LE (Radeon8500LE) and the TV-out on it has been acting wierd lately. When watching a movie (DivX, Xvid, or DVD), the image outputted to the screen kind of seems to split. It's hard to explain, but it looks something like this:

Copy and paste the shortcut into the taskbar to view

See what I mean? It looks kind of like the image is a little bit split. I've checked all the cables and nothing seems wrong. Any idea what it could be?
 
I think i know what you are talking about though, sounds like bad interlacing issues...

Does it seem to split approximently halfway down the screen?


EDIT: Oh, okay i see the pic now... hmmmmmm............ it still sounds a little like the video timing being off, have you screwed with settings lately?
 
I don't think I've messed with the settings... any messing I have done has already been reverted to factory defaults. The video plays fine on the computer monitor without shearing.

EDIT: I reverted the flicker removal to factory default (under Display -> Advanced -> Displays -> TV) and it made things a little better... I need to test it some more on other video clips.
 
Yes. That would be correct. The video clips play fine on your monitor, but not on your TV, because your video card has to interlace the image(1/2 the image 60 times a second, compared to your monitor which displays progressive scan[60 or more FULL images a second])......... so the problem is somewhere in the conversiont to the interlaced image.


Try screwing with some of the timings of the TV out using powerstrip.
 
From my experience its because the video card can only have 1 overlay play perfectly on 1 output. With my Geforce4 4200 if I have my monitor set to primary display divx/dvd/etc that use overlay shears on the tv. If I set tv-out to primary display, it will shear on the monitor and play perfectly on tv.
 
Ig - I think my video card is the same way. I guess I just didn't notice until now. 😕 So anyway, I did some working around in the Display control panel and got hotkeys rigged to toggle between Monitor-primary/TV-secondary or TV-primary/Monitor-secondary. Works great. Thanks! ^_^
