This is weird; never seen anything like it before. About a week ago, I received in the mail an anime series I bought. I put the first disc into my computer and it played perfectly, so I watched a couple episodes. After that, I put the computer into hibernation. Came back, went to watch another episode, and suddenly i get this error: Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card.
Huh? I just watched it! No matter what chapter I try to start the DVD on, it won't play. So I try Media Player Classic. DVD: Copy-Protect Fail error. Realplayer SP and Quicktime don't even play DVDs (Realplayer will if you pay for it, but forget that). I would have downloaded another program, but was convinced it was unnecessary because the thing just played 15 minutes ago. Okay, fine, I downloaded the latest graphics card driver (which I'm pretty sure I already had), installed it, restarted...BAM! DVD plays fine. Okay, cool, I'm happy. Watch some, hibernate the machine. Come back later, and the same thing happens! Reinstall the driver, restart, everything's peachy. :weird:
Anyone have any idea what's going on? I've played DVDs in this computer before without issue, so what gives? The DVD plays fine on a normal DVD player. I also know that it's not a bootleg DVD. I'm guessing it's a graphics card problem, since reinstalling the driver fixes it (which stinks if so, because this is my laptop), but is there something else I could try to fix this? Or is there a good DVD playing program I should use instead of WMP or MPC? Thanks in advance.

Sounds like you've hit (
http://support.microsoft.com/kb/935466/) this problem. I would guess it's down to DRM measures and the "Protected Video Path" failing because Windows has a problem when verifying if it's been tampered when you go in or out of hibernation (but that's just a hunch).
I suspect that until Microsoft fix it the safest thing is only go into hibernate after closing your DVD player software.

That seems to be the same thing. Odd that they don't have Windows 7 listed as having the problem. Also odd that it affects MPC as well as WMP. Thanks. Maybe closing the program first will help; I'll check.
EDIT: Heh; what do you know, that did it. A tad annoying, but better than nothing. Thanks. :)

Well, that only circumvented the problem the first time. Now, even if I close WMP before hibernation, I still get the error when trying to play the DVD and still have to reinstall my graphics driver. Any other workarounds I could try? Thanks.
