Can anyone tell me if the new ATI MMC 7.6 supports 24-bit AVI capture?

What program/method can be used to reveal the bit depth of an AVI file?

I capture using an ATI All-In-Wonder Radeon & use TMPGENC to compress to a VCD compliant MPEG file. I would like to capture to AVI, edit in VirtualDub & then compress to MPEG.
With MMC 7.1, I get excellent clarity in my final VCD, but I can see the problems with the 16-bit AVI & am wondering if the new 7.6 solves this problem.
