dvd playback

[colin]

Hey mvpaaagh,

the method I suggested does not alter the video quality, as I am transcoding at 100%. In other words, it leaves the video untouched and basically demuxes it. This took about 10 t0 15 minutes for Empire Strikes Back (2hr film), followed by about 8 minutes to convert the audio from ac3 to mp3, then about 5 to 10 minutes to run through mplex to create a playable mpg on the MVP.

To me for those wanting to watch a DVD over MVP this is about the fastest (free) way of doing it. Of course i need to check if you need to use DVDDecypter before using rejig. If you want to reduce your video in size, then you can do this but remember, this is transcoding.

Now, if you where to recode this, say using CCE, then you are talking 2 to 3 hrs, plus audio converting, and plexing on top of that.

This is a whole different field of information and to learn more about this i can suggest several good sites.

I suggest trying your 6 minute vob this way and see what the quality is like in comparison to your method,

cheers,
Colin.

Colin,
thanks for that. The timings you describe sound pretty good. I'll certainly give it a go. I think all of my attempts involved some form of resampling or reencoding of the video stream. I guess this explains the crazy conversion times I was seeing.
thanks again,

Colin -

I've tried your methodf and it works well. However, I can't figure out how to launch rejig from the command line so I can't automate the conversion process. I have been able to get BeSweet and MPLEX to work from batch files. I was thinking of trying to modify the DVD ripper plugin to do the conversion to mpeg automatically so that ripped DVDs could be played on the MVP.

Thanks

I agree, it would be nice to see the DVD ripper plugin modified to automate the process. Keep us up to date on any progress. I'm sure alot of users would like this functionality.

try in a CLI typing rejig /h (or whatever the does flags are). I'll take a look today through doom9.org for the options as DVD REbuilder uses rejig.

Of course there are probably other demuxing utils out there to do this, but i'll see what i can dig up. The nice thing with rejig is, if you want to reduce the file size, you can it quite easily whilst maintaining good quality.

Cheers,
Colin.

As you no doubt found out too, trying rejig /h didn't help. I dowloaded the source and looked through it and couldn't find any command line switches documented that would let me do what I think I need to do.

That said, I do have a working prototype of a plugin that converts DVDs to MPEG files. It goes through a 3 step process
1) RIP and demux the first VOB file on the DVD using DVD Decrypter in IFO mode. I'm not really sure if this is correcting for the time delay like rejig does or not. It seems to work thus far however in the videos I have looked at.
2) Transcode the audio using Besweet
3) Recombine everything using mplex.

I've run it on a half dozen or so DVDs that I had already stored in ISO format (via DVDDecrypter and/or DVDShrink) and mounted via Daemon Tools and so far so good.

I also have written a plug-in that replaces the built-in Recordings plug-in. My plug-included the functionality to archive old recordings (including the show description information) out of the GBPVR DB and recordings directory into a different directory/drive (via a service that runs once a day). It then lets you browse archived records only, archived + new recordings, pending recordings, or DVDs (that have been converted as per the above plugin) It lets you sorts records by date (newest first or oldest first) or, in the case of DVDs, by name (from A to Z or Z to A).

I don't have a web site so I can't post them anywhere, but if someone wants to be a Guinea Pig and try them out let me know.

Possibly this was removed but DVD-RB uses it so there must exist a version, but there are other demuxes available.

I doubt DVD decrypter will adjust the audio but besweet can do this, not sure if decrpyter informs you what the delay is though.

i can take a look at these for you if you want,

Sure, how do I get the files to you?

[Guest]

I've sent my plug-in off to sub for posting along with another one that manages the recording and DVD archive. I've also included the source. It is my first attempt at c# and .NET programming, so all suiggestions on how to do things better are welcome. I've also written some utilities to pull movie informaiton of of the intenert for the ripped DVDs and to autodetect when a DVD is inserted nto the drive.

I see in the video archiver pdf file that you need

Installutil.exe

none of the XP SP2 machines, which have .net on them, have this program ?

does it only come with the SDK ? where do I get it ?

Should there be a similar line to use InstallUtill in the DVD 2 MPEG section of the PDF ?
