Playback of QT files on data DVD

[rumigirl]

Sorry, guys -- here comes another silly newbie question.

I've backed up some media files -- some QuickTime files -- to a data DVD. When I play the files on the data DVD to make sure they copied okay, the video plays correctly for a moment, then starts to stutter, and then freezes; the audio, however, keeps going. If I stop playback of the file, the frozen video image disappears and the correct video frame comes into view.

So it looks like the file is not corrupted; it looks like I'm just having playback issues. Is that true? Am I seeing the freezing and the stuttering because my system has to go out and retrieve the data from the DVD drive (I have a dual-processor G5 and a SuperDrive)?

How can I prove to myself that the files I've copied to the data DVD are okay? Do I have to copy the file(s) on the data DVD back to a "regular" external hard drive or my system drive and play them from there? Or is there an easier way to test them?

Thanks much.

Yes, I run into this a lot with my PC.

Copy the files from the dvd drive to your desktop. Files should play fine once on your hard drive.

There is most likely nothing wrong. QT has difficulty playing large files of large pixel dimensions. (Prior to QT 7)Go to Movie>get movie properties, Select video, toggle down to frame rate. If it's 29.97(ntsc) your OK.

Thanks, you guys.

Dasonras, I finally just copied the files from the data disk back to my internal hard drive and they played just fine, just like you said they would.

Vidwerk, can't find those menu items. Are they in QuickTime? Anyway, no biggie either way...

They are in the top menus of QT. Release 7 has moved stuff around for the worse.
