Further to my previous post, I’ve spent more time investigating this problem. Using firewire and SD (DVCAM) footage, I get perfect frame-accurate results digitising from my Sony HVR-M35 deck. When i put an HDV recorded tape in the deck, it all goes wrong! I still have transport control, but get no audio/ video on firewire. If I use SDI for video, either SDFI or AES/ EBU for audio, I get signal in OK, but device control on firwire is random, nowhere near frame accurate. I’m stumped with this one, and so far, so is the dealer who sold me the system!
