VK,
we must be travelling in parallel worlds; I've spent each evening over the weekend tweaking the lipsync following my SDI mod. (I was right there with you again when trying to work out which screws to undo to get inside the 598). The possible combinations of delay between presets, sources (advanced) and video processor have had me questioning myself several times.

It has shown me that not all programmes (TV broadcasts) are produced equal!

I can't remember a section for lipsync on my (quite old now) DVE DVD but I'm going to check.

Otherwise it will be out with the Matrix as Mark suggests.

598DP SDI, 568.25MM, Crystalio II 3800, 435 XDE (soon to be 50pf20?), NVA A80 x 8, AE2's, AE2 Pro, AE1's.
