iam not 100% sure its correct, ive checked the spec and its not really
clear. There are 2 things normally,
1. if the video content is interlaced
2. how it is compressed/stored
The spec doesnt clearly seperate these ...
so the code might need finetuuning later if our interpretation of the
spec is found to not match actual files ...

patch applied, thanks
