FYI Using the LaHo DNS is working nicely for me. DVArchive is happy now that the RTV's time is correct, so I'm able to transfer the videos without having to remove the HD. FWIW the bandwidth on the YWA-10 isn't great for me, and the USB jack on the back of the RTV won't power it so I had to hijack a phone charger. But it is working. And DVArchive's memory footprint is much smaller now that it doesn't have to store five hundred channels of programming data in RAM.
Again I'm grateful for your guidance and suggestions.
