My computer has a wonderful habit of going into a coma and not waking up after sleep mode.

I rendered a rather long m2v stream last night. Usually make selection, render wav, then render video stream (i have VV3.0c).. then out to DVD

But.. rendered video stream first, then computer crashed, so i lost my selection.

Anyone know how i can get the exact/accurate length of my m2v file so i 'recreate' my original selection to render the audio file?
- they need to be the exact length for sync (i believe)
My DVD authoring program only gives length to second, not tens/hundreths


thanks
