Herb, thanks for you post. My DVR is the HR-10 250. Hopefully it will be different than the prior model DVR. "Anywho," I found the Canopus ADVC110 that I bought 2 years ago to use with my digital camcorder and my PC, before I switched to the Mac.
Canopus tech support just told me precisely what you said, so I know that this will be a viable option. But I would much prefer the USB approach to copy the file directly, because that would give me cleaner video.
I'll keep you posted.
