I know, it's a shame that JVC stopped making and selling these machines. Fortunately, I have two (40K and DT100U) which I hope will last forever. Otherwise, only re-sales of these used non-new used machines are your only hope, and then who knows what you're getting. Luckily, there are still sources for blank JVC DF300/DF420 DVHS media which I still buy once a year or so.
Anyway, I'm not sure I understand exactly what your first question is asking. The "copy once" designation applies to DVHS tape, not the recording on the DVR. So when you archive from DVR to DVHS, that's the first generation copy and is allowed... always. So you can always transfer any DVR recording to DVHS, even HBOHD, etc. It is pay-per-view which is "copy never" which cannot be recorded to DVR and also cannot be recorded to DVHS (in real time) via firewire.
I returned a Toshiba DVD recorder after it's copy protection circuit popped in on everything, even with signals coming through via RF cable!
Don't understand this, unless it was macrovision or something like that (imbedded in the content) involved here, which used to prevent macrovision-protected VHS tapes from being copied to VHS tapes (or, presumably, to DVD recorders now). If you were trying to copy something from DVR using an RF/coax cable out of the DVR (worst 480i video quality, of course) then it had to be some kind of analog protection mechanism, assuming there is a way for the content provider to apply that to the underlying content to try and prevent analog copying. I'm surprised they would bother with this, since it's the digital perfect copies that are really the prize.
However firewire archiving from DVR to DVHS is pure digital data transfer, 100% exact bit-for-bit copy. Not analog. And no analog protection system applies here. The assumption is that 5C protection (and 5C-compliant DVHS VCRs) will prevent duplicating the 1st-generation DVHS copy (which is permitted) onto a [perfect] 2nd-generation DVHS copy.
Note that the Moto DVRs allow for a setup option [AllTo480i] downconverting everything to 480i (including output to component video and HDMI), which activates the S-video and composite video outputs for HD (720p/1080i) DVR programs and recordings. So you can make an S-VHS/VHS copy of an HD program (recorded or live) on a conventional VCR. While this would be letterboxed 16:9 (in 4:3) and superior video quality to an ordinary 480i recording, it's analog and it's not HD. However it would also send the exact same 480i letterboxed 16:9 output (in 4:3 real estate) to a connected 16:9 HDTV via component video and HDMI.
Any copy protection circuitry in your now-returned Toshiba DVR recorder would have to be located there (since it's not in the analog circuitry of the DVR), and based on the presence or macrovision or similar analog security mechism in the actual program content.
