iam not sure what value to check for what, the app marker is 16bytes
in ntsc.avi the patch causes a byte to be read that is not part
of the app marker but outside
If you intend to read that byte thats probably part of the
AVID comment and would need to be read from mjpeg_decode_com()
the len (61) is probably also parsed corectly there and available for

I dont mind to finsh it if you prefer but i dont know why you check
that byte or if its even that byte that you wanted to check ...
