hi john,

the flv file specification has not changed in flash 8. its the same as in 
flash 7!

you have the same tags 09 = video, 08 = audio as in flash 7.

i simple use the vp6vfw.dll to generate flash8 videos with the "old"
flv specification. but on2 dont gives the legal rights for this in their
licensee of the personal vp6vfw licensee.

message me if you have any questions. i would like to help to include
the vp6 - flv playing feature in mplayer.

kind regards
gary, germany
