Laptop DVD playback is blank on second screen
I'm using the InterVideo WinDVD codec (Is that the right term?) on my Dell Inspiron 5100 on a Radeon 7500 (32MB). When I use dual monitors and "extend my desktop to this screen" I can't watch DVDs on the second screen. I can drag Windows Media Player (8) to the second screen/TV but when I do I only see a black screen. All of WMP shows up, I can use the buttons, but the playback area is blank. If I split the window so half is on my laptop's LCD and half is on the screen/TV and I can see the the part that's on the LCD but the other part is still black. I can (with a bit of struggle) get my LCD and second screen to display the same image (so Windows thinks it's only using one screen) and then the DVD playback works. This isn't convenient because I'd like to work on my LCD (higher res) while watching a DVD on the external CRT. My friend has a Gateway laptop with a Radeon 9000 and he can't get the DVD to show up at all on the second screen no matter what. Any ideas?

(The problem also happens if I use WinDVD's native player)

I accepted your answer just because you used the word "Macrovision" and it immediately cured my I-don't-know-what-to-type- into-Googl e woes. Macrovision just scrambles the video out signal, this is done at a software/driver level as it doesn't work on VGA-out to a CRT screen. XGhost doesn't fix this problem because it isn't a Macrovision protection thing.
