Re-merging AVI's with AC3

[Cyberia]

Lets say I want recombine a multi-disk avi to the local hard drive. Lets further compound the issue by saying the avi audio is in AC3 format. The final AVI will also be larger than 2GB.

The only solution I can see is Nandub, setting preload and interleave to 96/96.

AviMux cannot accept other AVI files as input can it?

The Nandub solution works great for me, but so many people say that Nandub does not handle AC3 well. I am using SPDIF output. Video and audio stay in sync, are not jerky at all.

What other choices are available to do this?

Oopsie, I forgot to say that I have tried VirtualDubMod also, and it works fine too. But I know they pulled the AC3 sections right from Nandub...

Nandub also has a much smaller disk footprint than VDM, which is important, since I am cramming as much stuff as possible on a CD.

It would be worthwhile to use VDM anyway if it produced more compatible AVI/AC3 mux's. However, I don't see an overwhelming opinion on the boards either way.

What exactly is the problem with Nandub and AC3? Is there any actual basis for setting Preload and Interleaving to 96/96 (or 160/160)? I don't mean to get off topic there, but I want to understand what the nature of the problem is.

Thanks

@Cyberia: What you want should work with AVI-Mux GUI. Of course does it support other AVI files as input...it accepts any valid AVI, WAV, AC3, DTS, MP3 (and, beginning from 1.12.2 and the soon coming 1.13; just running final tests) SRT files. AVI files can have as many streams as you want (i've tested up to 9x audio)

The problems with AC3 are actually mega-crappy filters and/or drivers and/or decoders, which react to "splitted" AC3 frames differently from what the AVI file specs require.

Note that AVI-Mux GUI requires that you activate Open-DML output for such large output files.
