Aha, i hadn't noticed the sync to mtc playmode before you mentioned it. So odd that you can spend so long looking at an interface and never actually clock what's there.

Just need to persuade the venue to purchase the show control sfx license now so that i can actually get MTC from them to reference too.

Though in fairness i have done a lot of testing over the last few days and i haven't yet managed to get the audio/video to slip out of sync. So potentially this may not be required.

Thanks for the help!!

Cheers

Gareth
