DVD coasters from mp3 re-encodes

[alvin grung]

I am starting to waste a lot of dvd's when I use ffmpggui or besweetgui to reencode mp3 audio. I can't figure out why some files pose no problems and others are a royal pain, either refusing to transcode or causing sync errors. But lately my problem has been files that :

a) look and sound fine in tmpgenc dvd author,
b) burn fine,
c) play fine in PowerDVD, then
d) have no sound in my JVC XV -S300 player.

I note that the receiver uisually shows a led display of my speakers, but I lose them when I put one of these discs in.

Is this because the files are really still mp3's with different headers, that aren't fooling my player? If so, why are they different and is there a solution? It's getting expensive. thanks.

MP3 is not a DVD-Video or DVD-Audio format.

Sorry, I guess I wasn't clear. These are transcoded from mp3 to ac3 and mp2, but neither will play in my JVC DVD player.

First - neither of these are using licensed technology, so there are no guarantees of compliance.

Second - if these were VBR mp3, try using virtualdub to save them out as uncompressed wav files, then converting.

Third - when you are having difficulties like this, it pays to burn to RWs first. It takes a little longer, but no coasters.

Thanks, they were vbr. Saving to wav usually works, but not always, as per your #1 point. I will get a few rw's, but I have heard that they don't play terribly dependably. Is it worth it as a test medium just to give you an idea of whether your file is burnable?

I use TDK rewritables to test navigation and to look for quality or sync issues. They have never let me down.

Yes RWs are good way to avoid coasters.

Check the bit rate you are using for the audio encoding. It should be mp2 compliant. Try to re-encode you AC3 files for 2 channes rather than for 5.1 channels.
