HI all, i'm trying to parse an avi file following avi file reference i've found in the net but i'm finding some structures in my file which doesn't match the expected format.

Can an avi file have several 'movi' lists?
My file seems to have an old avi index since it has a fourcc 'idx1', but every index entry is 32 bytes long. Is that correct?, Where can i find this 32 bytes long entries structure pattern to parse them?
The video an audio info is organised in rec lists, and the chunk id for chunks inside the rec lists is xxiv, which doesn't match any of the ids i've read about (db, dc, etc). Can you tell me what type of chunk it is?

Thank you so much for your help
