View Full Version : DVD Playback gives Key Exchange Error
08-08-2003, 09:59 PM
I just upgraded to 1.4.7 and I add the Video Library Import folder of F:\ and when I goto the Video Library and select the video_ts for playback I get the following error:
There was an error with DVD Playback. Key exchange for DVD copy protection failed. Can't playback this DVD-Video Disc.
However, I have 2 different dvd playing apps installed and they all work fine. I changed the video codec being used in sage setup to the cyberlink one and that does not help. Anyone have any ideas what my problem could be?

I think you've got a DLL version mismatch. Remove Sage and then re-install it (a new version 1.4.8 RC1 comes out today, so you might as well just use that)

I just uninstalled 1.4.7 and installed 1.4.8 RC1 and I am receiving the same error. This is using the default Hauppague decoders.
> This is using the default Hauppague decoders.
Do you have any other filters (e.g. from WinDVD, PowerDVD, etc...)? I'd try those...

The default Hauppauge decoders are "NonCSS". If you don't have a CSS decoder, than this error message will occur because the decoder isn't capable of decrypting the DVD content.
You need to get a CSS capable decoder. All of the regular DVD decoders are CSS capable, i.e. WinDVD, PowerDVD, Cineplayer, etc.

Unless of course you're trying to watch a DVD disk (or DVD files) that don't have CSS encryption. Then you wouldn't have any problems using that video decoder.

OK-Now I get it. So that's why when I installed Sonic Cinemaster codecs it worked fine. And If I rip a DVD using Decrypter (If I did that sort of thing ) the default Hauppauge codecs would work. It didn't occur to me what the Non-CSS meant in those drivers. Thanks for the clarification.

Should one be able to pick a "powerdvd" decoder for DVDs or should it work as long as powerdvd in on the machine?

If you've only got one kind of CSS capable DVD decoder installed, then you can just pick Default for the decoders in DVD and it'll use that one. The Default for DVD is not necessarily the same as the Default for standard MPEG2 files, it's usually different.
gplasky, You're probably right about the decryption (not that I'd know).
There's a legitimate use of non-CSS capable decoders anyways. If you author your own DVDs, they won't be CSS encrypted so you don't need a special decoder to watch those. So for non-CSS encrypted content, you can use the Intervideo nonCSS decoders or even use the Elecard-DScaler combination.
And likewise, if you author DVDs, and you initially have them created as a set of files on your hard drive, you can just add a parent folder of that to the library import path and it'll show each of those DVDs in the video library for SageTV.
For example, if I've got:
where those video_ts folders contain all the vob, etc. files that are found on a DVD. Then I can add D:\MyDVDs to the library import path and VegasTrip and Chicago will both show up in my video library, and will be fully watchable without having to burn them. You can just select them and it'll essentially play the DVD from the hard drive.
I AM IN NO WAY SUGGESTING THAT ANYONE USE THIS TECHNIQUE WITH DVDS THAT ARE COPY-PROTECTED. As there obviously are legitimate uses for importing a set of DVD content from a hard drive as explained above.
