DVD and Security Certificates

[Song Tae-Hyun]

I went through and deleted EXPIRED security certificates in Internet
Explorer and now I can't playback DVDs.

How do I repair this? Why do EXPIRED security certificates have anything
to do with DVD playback?

Restore doesn't work, since they don't keep track of these files.

Hello,

I am sorry that i can not understand your question.
Please give me more information about the DVD.

*for example : IMAX WMVHD VIDEO

Originally, I thought it was something I did. As it turns out DVD play back
on almost all of the machines at home, no longer work. My neighbors
computer as well.

I'm not sure, but Windows/DVD player used to ignore the security feature on
DVDs preventing them from copied so it was easier for everyone to play DVDs
on Windows. Well, now it seems MS has turned on to the security feature
and DVDs won't play on Windows Vista or XP.

Update:

My mom's HP/Compaq laptop will play DVDs after I installed Interactual
Player, go figure.

Or you can circumvent the whole security issue by using AnyDVD or DVDidle.

CDs and DVDs are either security locked or they are not. Not system can over
write in the normal way. MS does not have a security lock on your DVD
player or burner either.

Whatever system of software or hardware you use need to burn slowly and
complete a what is KA a finalize sequence, lead in lead out. If this does
nopt happen they will never play.
