Team,

Sorry to bother you but I really need some help here as I'm stumped.

I recently obtained some MP3 DVDs with many collection Cds ripped to MP3s. The DVDs all play fine on my PC but when I try to make CD sized versions (after copying all of the Files to my Hard Drive) they play fine on the PC, but gives me an error code on my JVC Car unit almost like some of the files are write protected, or format not supported (According to the JVC Manual that's what the error code means. This unit doesn't play MP3 DVDs that's why I'm burning Cds ) .

It's weird as over half (7 of 13 MP3 Cds) of the Cds play fine but 6 of the Classic Rock MP3 CDs all play the first File in each Folder (each folder is a complete CD - there are about 10 Folders -Cds on each disk) but the remaining files all come up as file format not supported (protected??).

I think it's something to do with the codec used to decode the original files (from the CDs). According to Windows Media Player , the first files all seem to be MPEG Audio Layer-3 @ 160Kbps, but from the second tune on - in each folder - they've used an MP3 AC3 codec of some sort. (Which I don't think the JVC Head unit can support.)

Any idea on what software to use to convert these MP3 AC3 encoded files to regular MPEG Audio Layer 3? I've tried Nero but it will only load the "good" MP3 file and gives me an error on all the rest. It would be great to batch convert them rather than individually but for now I'd try anything you know that works.

Thanks for the assist.
