Sorry for delay. Please test attached patch.

A few notes:
- the "skip other header crap" is not really needed for any sample i
have
- the fourcc read could be replaced by a 5 byte skip for every known
sample that have fourcc
- the buffer size was increased for correctness only (max string len
is 255), not for safety (str_8() can't overflow the buffer). No known
samples have long strings anyway.


I plan to apply this no later than this weekend.

Ciao,
 Roberto
