View Full Version : 2 audio tracks muxed, cut, burned: only 1 audio remains...?

Using DVD2SVCD I've made several 2 language SVCD's without any problem whatsoever. Now that I'm making a DivX -> SVCD with two audio tracks I keep hitting an invisible wall though.

My original French audio (96 kbits MP3) done to 96 kbits 44.1 MP2 with TMPGenc. The English audio (DivX Audio) done to 96 kbits 44.1 MP2. Both play well in media player. Muxed with both TMPGenc and BBMPEG (to be sure that wasn't my problem). Cut large file into a 15 minute file to burn to CD-RW to do a quick check on the Apex 1500 standalone: only 1 audio plays. My 1st track was the french one so I thought maybe the english track is defect. Muxed 2 x the french track, cut with TMPGEnc: same result, no second audio track.
Sample(s) show 192 Kbits for audio in TMPGenc (which could be the 2 x 96).

Samples were burned with VCDEasy and NERO, both giving me the same problem.

Oddity: WinDVD's right-click menu shows an Audio 01 and Audio 02 entry for the cut sample - not for the original big file.... And of course when Audio 02 shows as an option it is a silent track....

Anyway, the only thing I can come up with now is that cutting the muxed file with TMPGenc kills the 2nd audio stream? If so I'm not happy: muxing the complete movie and then cutting it would (I hope) prevent audio sync problems.

*sigh*... this *should* be simple, right?

I heard (and experienced myself with PowerDVD XP (4.0) and WinDVD 3) that software DVD-players don't yet support/can play the second audio stream from SVCDs.

On a standalone DVD player(in my case Philips DVD752) the second audio stream works perfect.

Hallo Eindhoven :-)

Yeah, I'm aware of that. What I know from using DVD2SVCD is that my standalone has no problem with dual tracks. However I seem to be unable to produce such a SVCD myself. Muxing with BBMPEG according to the guides. Then I cut the file. Then burn it: tried VCDEasy and NERO. In both cases: no sound for track two.... Only thing I can think of now is that you cannot cut a dual-track MPEG... :-(

Why donīt you cut while muxing with bbMPEG.
Simply give a max file size and bbMPEG splits automatically.

On the other hand you can cut perfectly svcd.mpg`s with 2 languages with DV-Tool.

Search with google and go to combatmans site ...

Thanks MB1 !

I'll give that a try first thing tomorrow. I obviously haven't examined BMPEG the way I should have.

(I readed your first post to fast, i missed the Standalone part)

I too think now that mb1 is right, i think TMPGenc can't cut mpeg-streams with 2 audio streams.

Succes Canada!! ;-)
