Mux tool fail

[Guido]

Hy,
I am trying to use the mux tool of FFMPEGX 0.0.9. Here's my process :
Source files :
mpeg-2 (m2v) for the video.
.AC3 for audio.
Using a -10ms sync correction (found out that audio is correctly synchronised with this setting after several test)
Mux as DVD
No post process.

I get a .mpg file that work fine but :
It look like the process don't go to the end. The process report something about needing to split but don't find a %d pattern

**ERROR: [mplex] Need to split output but there appears to be no %d in the filename pattern /Users/***/Documents/***/Video et image/FILM1.mpg

I checked my .m2v stream with VLC. Looks ok
Currently checking the .AC3 (in case it would be cut)

I am almost sure the problem come from my source stream, but I can't find out what could be wrong.

Any suggestion or remark is welcome.

Thanks.

Ok, I found out a way to get around my problem :
I reencoded my .m2v (witch is mpeg-2) to .m2v (mpeg-2) using mpeg2enc setting and no audio.

Hours later I tried a mux process using the new .m2v and the old .AC3. Now I get throught the all stream without errors. (except for the sync problem now audio is slower than video)

Only I guess I have a worse quality for the video (since the new .m2v is only about 1,8Go for 2,9Go for the original). I don't see much of a difference on my 12' PBook.
