Lion and iDVD (November 22, 2011 07:07AM) SAD
Hello all..

I had to author a dvd with a menu on the fly and so I imported a QT movie in iDVD and made my DVD. I tested it on a DVD player and it worked fine. I sent it to my client who tried to play it on three different computers (two pcs and a mac) and it didn't work. When the client played it in the dvd machine---it worked.

So, my question. Why? Does this have something to do with Apple phasing out iDVD and therefore it isn't working fully with Lion?

My iDVD is from Snow wasn't purchased after Lion download.

Any thoughts?

My first suspect would be the brand of media you used. Many computer DVD drives don't work well with low/no quality brands like Memorex. They simply won't read the disc properly.

My second suspect (for the Windows computers only) would be the DVD playing app they tried to use to play the disc. Most people try to use Window Media Player, but it really sucks at playing DVDs. Apps like CyberLink's Power DVD work much better.

Thanks, DH.

These are high quality blank DVDS that I always use---so same stock as always.

I will ask them how they tried to launch the DVDS in the Windows PC. The client did say on one of the computers she could hear the audio--not the video.

I had her double click on the disc and tell me what what is in the VOB folders. It was just wording about permissions...?

Lets think:

- She hears the audio -> This means that the disc can be played and only the video cannot be decoded.
- The disc plays in a regular DVD player -> This means that the video codec is correct (there is only one codec for DVDs).

I think that the used DVD player software (probably "Windoze Media Player") is malfunctioning.

Ask her to play the DVD in a regular DVD player or play it with Power DVD.

Correct, I mis-typed. I meant to say Video_TS Folders.

I do think it might be a playback issue on the windows computers...but why on a mac? I wasn't in the room with them as they tried to play the dvds.

So---no one thinks it may be a Lion-iDVD compatibility issue?

>>I had her double click on the disc and tell me what what is in the VOB folders<<

There shouldn't be any VOB folders on a DVD video disc. There should only be a VIDEO_TS folder and optionally, an AUDIO_TS folder. Inside the VIDEO_TS folder are where the VOB files should be located. VOB files are specially formatted MPEG-2 video multiplexed with audio (PCM or AC3).

Correct, DH, I mis-typed/mis-spoke

I can understand a windows issue...but why the same problem on a mac?

Also---no issue at all regarding Lion-iDVD compatability issues?
