I was just meaning that I'd prefer not to have to convert back to analog once the signal has been processed digitally by the DVD recorder. Not a big deal, I know, especially for my source material. And I guess it's no different than VCRs that use digital buffers for TBC. If a filter couldn't be found, I was actually considering buying an old European Panasonic DVD recorder. I'm just not sure which models carry this same type of TBC and I may have an issue with finder sellers that will ship them to the US. This might be my best option, so I'll be looking into it.

Shame there isn't a filter. Seems like it could be a pretty simple one. It would just need to examine where the picture edge of each line is and then nudge them into alignment. I'm not talking large amounts of adjustment. Much less than is needed for stabilization filters and such.
