Can't play DVD. Always get "

I am using MPC-HC 64-bit 1.7.10.276 (e15495d) on Windows 10 64-bit, trying to play any Battlestar Galactica (2004) DVD. I installed MPC-HC from the "Mega" pack, K-Lite_Codec_Pack_1280_Mega.exe

It plays the "Universal" logo/intro thing.
It plays the "The opinions expressed are not those of blah blah..."
It plays the FBI Piracy Warning.

Then it stops, and at the bottom of the window reads "DVD: Copy-Protect Fail"

I read in the FAQ about changing the output under View > Options > Playback > Output.  I've tried changing those, but none work.  Help!

TIA!

Another cause can be if the region code of the DVD does not match with the one set for your DVD drive.

Do other DVDs play correctly?

Thanks. I can play the DVDs with VLC. Also, the DVDs play in my standalone DVD player (not region-free) for my TV.

I just tried playing two more DVDs (I have all region 1 discs). Both play with VLC and in my standalone player, and both played with MPC-HC.

But I tried two more discs from the Battlestar Galactica set, both of which play in my player and VLC, but neither of which plays in MPC-HC.

MPC-HC uses the DVD Navigator filter from Microsoft for handling the DVD structure, while VLC uses its own which is less strict. And no, the one that MPC-HC uses can't be changed.

If other DVDs work correctly with MPC-HC, then I unfortunately don't have any solution for you. At least no for playing it directly. You could try AnyDVD, that might be able to remove the "protections". Or rip the DVD to harddrive with DVD Decrypter.
