Has anyone ever gotten this message "PREVIEW UNSUPPORTED FOR THIS FORMAT" in the FCP Log & Transfer window?

I've been logging clips for over a month but suddenly I'm not able to preview and set in and out points.. very frustrating to say the least...

FYI - Mac G5 Quad - footage shot with HPX500 at 720/24pN -

clip files are on an external 800FW drive -

same thing happens when I try the backup drive -

one file on the drive that I had already ingested now gives me the same warning but was fine before -

files on an earlier drive are okay -

I can ingest the clip, that does work, I just can't preview it/them..

yep, that is happening on some of my backup files on a drive.

Weird, huh?

Have the moderator move this to the Mac forum and, you should submit a trouble ticket to Apple Pro support on this; I'm sure other FCP users would like to know of this glitch or, be aware that others are having similar problems.

Could you be overloading your FW bus?
If you have any other FW devices plugged in, try unplugging them first (and try restarting FCP and/or the computer).

Thanx Jon, but no, the material works with one drive and not another (using the same Granite 800FW tray drive)...

I'm wondering if I somehow formatted the drive differently because the original files (done on the road to a portable 400FW drive) work fine - it's only after I transferred them to the 800 drive that the problem occurs - and continues to occure downstream from there...
