>> To avoid frame dropping, you need an external TBC (different from the TBC in the VCR) acting as a frame sync.

Let me add for the person asking the question that I found an external TBC extremely useful back when I was transferring family movies from VHS. Even though I used a nice SVHS unit with an internal TBC, some of the worst older tapes still had lots of dropping out, tearing, and sync issues that magically all but disappeared when I fed the signal through the external TBC. Perhaps you don't need it in your case, but I definitely did.
Here's an in informative thread where someone asked about the need for an external TBC. Be sure to look at the images in post #7.
If I have a VCR with TBC, why is a separate unit needed anyway?
