Probelm encoding 2ch ac3 to mp3

[bugmenotwillyou]

this ac3 stream i'm trying to transcode is from a non-professionally made dvd (the dvd was fabricated from a VHS tape source).

i'm clueless as to what's causing it to crash every time i run the trasncode, just seconds after starting. when it's done i'm given an incomplete mp3 about 24 seconds long, same size and length every time.

perhaps this is the error causing my woe, but i don't know what to make of it;
[00:00:31.290] E33: Illegal symmetric 7-level value =7

any advice? thanks a lot

[mic]

I'm far from expert on this, but while waiting for someone knowledgable to post, have you tried any of the ac3 repair utilities?

[bugmenotwillyou]

didn't know any existed mic.. sensible suggestion given that it was a home-grown ac3...

i'll give it a try

[prOnorama]

I was having a similar problem when trying to encode a movie with GK.

The 448 Kbits ac3 stream would not be converted properly and aborted at 18 minutes or so instead of 2 hours 9 minutes 20 secs or so.

I more or less solved this problem this problem by transcoding the ac3 to WAV first with BeSweet, as you notice the error messages are still there but the trancoding process successfully completed.

Then I transcoded the WAV to MP3 without porblems and muxed it into the GK_Movie file. :)

I have no clue what these error messages are about but my DVD was a retail DVD. Maybe I should have Decoded this particular ac3 stream directly to WAV with DGIndex.

Anyway maybe this might help you.
