Hi. I think I am having the same problem also.
Its out of sync when im capturing from my camera. I have tried it with the camera firewired into the external hard drive and then with the camera firewired into the computer. Having it straight into the computer seems to help a little, but it still loses sync gradually. If i stop the tape and rewind or forward it often gets back in sync but then i’ll randomly lose it again and there seems no pattern to it.
The clips when captured play fine so its not a big problem but its nice to have it in sync when capturing obviously.
