Importing an AC3 file, I've received this message:

Cannot locate a frame SYNC word at an expected byte offset. Data might be corrupted. (0xc1070042)

Any suggestions?


Tnx in advance :)

Sounds like an AC3 file problem, more than likely the AC3 is corrupted. I've run into a few DVDs that gave me the same error. What I did was decompress the ac3 file to *.wav and then re-encoded the *.wav back to *.ac3 with Sonic Foundry Soft Encode.
I've also heard of some people using like AC3Fix to fix the error in the AC3 stream which maybe the easier/better way of doing it.

Thx a lot m8.

Hi,

if you get the error at 99% import, just rip w/o the last chapter. I had a few titles where the last chapter audio was corrupt. The last chapter in this titles were just a few black frames with silence but avoided appropriately the import of the audio into Maestro. It's a kind of NEW copy protection ?

Curiously, I've met all of them already ;)

In "Crimson Tide", I had to finally convert AC3 to WAV and then back to AC3. Luckily, it was a Stereo track so I didn't loose the track as if it would have been a 5.1 track.

In "Planet of the Apes" I had to use vStrip as none of the other ripping programs would allow me to extract the audio from it.

In Disney's "Snowwhite" I recall the error mike mentions, I had also that "99% error" frames thing.

taken fro another thread:

Is a kind of new Copy Protection on several titles.
When this happens, most of the time the audio of the very last chapter of this title is set to a different rate which leads to this error message because it's invalid for authoring.

In this case the last chapter does not include any valuable content (not even a chapter marker for playback).
