Bizarre video problem with SD TV-out

[tk149]

EDIT: Problem solved by rbV5 - THANK YOU!

I recently installed a bunch of Windows updates through Microsoft's website, and then things went bad. Prior to this, everything worked fine.

Radeon 9800 (non-pro)
Driver v8.351.0.0 dated 3/2/07
Windows XP SP2, automatically patched with Windows Update
Windows Media Player and/or ZoomPlayer


I have my monitor and SD TV hooked up. Using the ATI Catalyst Control Center (v2007.0320.2241.38712), I can set the second display device (TV, S-video feed) to be the TV in either "cloned" or "extended desktop" mode.

In cloned mode, I can see my desktop and everything fine. When I play videos, they appear fine on my computer monitor. However, I don't see anything but black space on my TV.

Video "playing" on TV

Same Video playing on Computer monitor

In extended desktop mode, everything works perfectly. I just drag the movie player over to the TV part of the desktop and I can see the video playing.

Here's the really weird thing. PowerDVD plays DVD's perfectly in cloned mode.

I tried uninstalling the videocard in Windows, then rebooting and re-installing the drivers.
I tried uninstalling ZoomPlayer, and then re-installing.

I can't find any help on AMD's website.

How can I fix this? Help?

That is because ATI and NVidia cards have just one video overlay engine, which can be used on either screen but not on both.

Some drivers let you choose which monitor owns the overlay in Clone mode. Furthermore, the ATI chips have a "Theater Mode" wherein the video overlay runs on the regular monitor, while the TV-out gets just the video - non-overlaid and fullscreen.

If I understand you correctly, this doesn't explain why:
1. It worked fine in cloned mode before I updated Windows.
2. PowerDVD still works fine in cloned mode, but WMP and ZoomPlayer don't work.

Why: Software not displaying video on the secondary screen is configured to use "Overlay" to display video.


How: WMP; Enable "Use high quality mode" in video acceleration settings.
ZP: Use "Video Mixing Render 9" as the default video rendering filter.

This worked perfectly, THANK YOU! 😀
