6 channel AC3 is detecting as 5 channel

[Vectorferret]

I have an AVI file with AC3 audio. The file uses non-AC3 data to create a delay at the beggining of the file (a few seconds of it rather than the normal few milliseconds). Although ffdshow is playing it as 6 channel (5.1) audio like it should, most tools are detecting the audio as 5 channels instead (which is problematic). Is there a way I can make it read as a 6 channel AC3 file (and if possible, preserve the delay)?

As there aren't any better suggestions, yet :), how about recreating the ac3 only with silence at the begining equal to your delay?

Between the two of those, there's not much I can do with the file other than play it (using ffdshow to decode) without sacraficing the LFE channel, which although not critical, if it's there I don't want to ditch it.
