mad output tested for iso-compliance

Hi all,

I would like to know if anybody has done a testing of MAD decoder output for MPEG1 iso-streams
and compared them with the standard iso decoder(l3dec) output.

I find that si_huff.bit(this is an iso-stream) shows a difference from iso decoder o/p in the frames 4,5 and 6.Possibly it could be in the tables or in implementaion of huffmann in MAD.

If anybody has already cleared out thsi problem, please help.

Cheers,
Praseetha
