Here is a sample of a Sony SLV-N750 VCR -> GV-D1000 -> Firewire DV capture

Ignore the sound. I ran it through a gain filter twice and then noise removal. What kinds of things in these movies would be helped by a better workflow? I'm just curious to know if all my effort will be noticeable.

The first one is probably worse than the second. I thought that the GV-D1000 was performing some kind of TBC. For the age of the videos I thought it did a good job? I was also recording onto DV tape at the same time, just-in-case.
These are the type of videos I care about recording at the moment.
Based on what I've read here, the AG-1980P should be the best VCR. (home videos, a mixture of SLP, EP, SP) If that is the case, which additional TBC would be recommended considering the VCR already has a TBC inside? I understand that many of these devices are good at doing different things, and that some are better than others for specific applications. I've read quite a bit that the ES10 is good for cleaning up home videos, but why get an AG-1980 just to buy more external parts? Is my very low hour (less than ~30) SLV-N750 good enough to be used with some external TBC units? ES10 + TBC-1000, ES10 + DVK-100? I want the best results possible and don't want to try to save money (within reason).
BTW, today I watched a TBC-1000 get listed on
ebay for $80. By the time by brain had registered what it was looking at, it was sold. Less than a few minutes after going up!
