ok I had one idea what may do it.. so I did up a test page (no bi movies this time
)
It has 3 mpegs with the frame rates differed because that could be something that effects it idepending on the codecs you have.. I think.. I hope. These are all 16 sec to me.
If anyone has a wee bit of time to check em for me I would be really grateful (especially if you are someone who had them show as 11 secs.)
