In addition - with DV for example, I get</div><div><br></div><div><div>Error: failed to map EditUnit -1 in IndexSID 1 to an offset</div><div>Error: Truncating packet of size 576000 to 575469</div></div><div><br></div><div>
I guess what I am asking is, is this even possible?</div><div><br></div><div>Cheers</div><div>Steve</div>
