Any reason why a DVD-R disc plays on G4 but not iMac?

[gravesend46]

Just burned a movie on Traxdata media on my Panasonic DMR-HS2 which plays fine on my PC and also through Apple DVD Player on my Mac G4 Superdrive at work.

However, it does not play on my iMac Superdrive at home. Presumably they're both using Pioneer DVD-R drives, so is there any reason why this should occur...?

The disc image comes as DVD_VIDEO_RECORDER on my iMac, but when I click on it, it says there are no items and it's zero kb - no VOBs, no folders, no nothing, which clearly isn't the case as it plays OK on my work Mac...

A presumption that needs to be checked.

My newer G4 came with a SuperDrive that was not OEM'd from Pioneer.

Running the application "system profiler" on both machines will allow you to determine exactly the manufacturer of the optical drive.

Other than drive incompatibility with the DVD-R media used, or possible missing software on the iMac, I have no clue as to why your movie won't play there.

Checked, and they are both DVR-104 Pioneer drives. My work Mac is OS9 and my home one 10.2.4 - maybe I'll update the OS and get iDVD and see if it makes any difference...

One question...

Have you used the region free patched firmware on any of them ?

I couldn't say about the work one, although system profiler does mention its firmware as being something like 1.4.2 (that's from memory so it might be wrong!) whereas the iMac's profiler doesn't mention a firmware at all.

Just noticed a similiar problem. Burned dvd-r's on a dual 125 won't play using dvd player on G4 powerbook but will play on all dvd players any other g4 and tv dvd players.

One thing I noticed was that Panasonic DVD Recorder discs don't seem to be recognized in OS X, but work fine in 9.

Check your versions of Apple's DVD Player software on both machines...
