I'm not following what you're describing.
Did you use the VCR as input to the HVR-2250 (via composite or S-video plus L/R stereo audio, from VCR to HVR-2250)? This is analog source (from VCR, say playing tapes) and is still supported (using analog inputs to the HVR-2250). And yes, it was and still is supported by WinTV, since old analog VCR's had composite/S-video analog video outputs and L/R-stereo audio outputs. So you could use the VCR to play tapes, and record them through WinTV using the HVR-2250. All analog.
However the DCX3510 doesn't have any analog video output. Only HDTV video output (either component or HDMI). There's nothing to feed the HVR-2250 as your old VCR did. The DCX3510 is for a modern world with HDTV and 16x9 images and users expected to be using modern HDTV's with HDMI inputs for best possible image quality of 720p or 1080i content, not 4:3 480i which is what VCR's record and play back.
And of course there is an analog antenna input on the HVR-2250 for when there used to be analog NTSC broadcasts OTA. But NTSC is gone now, so for the US the analog RF antenna input on the HVR-2250 is worthless. That's why you would use the second OTA/ATSC digital broadcast antenna input on the HVR-2250, if you wanted to record local broadcast networks via your roof antenna... if you had one.
Darn for not being able to hook up? Even with adapters?
How do people use their old VCRs, disc recorders, etc. to capture from DVRs? Or did this new DVR remove block?
If older model DVR's still had analog composite/S-video outputs (as they might have), this new DCX3510 certainly no longer does. Makes no sense to manufacture a unit with this connectors, if there are no TV's that can use those connections that current users still own and use.
Or, find a recording device that accepts component video input. But I would guess it mandates down-conversion of the HDTV content from 720p/1080i to perhaps 480p, while still retaining the 16:9 aspect ratio. I don't think there is an "Macrovision" analog protections being put out on the component video outputs from the DCX3510 (but I may be wrong, since I don't actually have one). There is only HDCP requirements on the digital HDMI output (for the cable and display device) as far as I know. It's the digital piracy the "suits" are worried about. They honestly aren't that concerned about the component video path.
I don't believe that aside from the no longer made JVC DVHS VCR's (which use firewire to feed them, and DO record 100% bit-perfect digital copies of true HDTV programs, offloaded from older Motorola DCT/DCH DVR's where it worked perfectly, and possibly from new DCX DVR's with the very latest software/firmware upgrades), you are not going to find an industry-approved recording device for 16:9 720p/1080i HDTV content. And with no analog video outputs being provided in modern DVR gear, the ability to record ANY analog content from a DVR is most likely truly gone.
