Are there any home- or prosumer HD video recorders with HDMI INput that use commonly removable storage like _
tape or Blu-ray RECORDERS? If so, then which ones do (especially those that are much-less expensive than Blu-ray recorders are now)?
And if there aren’t any home HD video recorders like that (again, I mean with HDMI INPUTS, not just cameras that can shoot HD and only record that), whether tape-or disc-based–even expensive Blu-ray, then why not?
If so, then which ones, whether Blu-ray or otherwise (especially much less-expensive than Blu-ray recorders are now, such as a high-definition prosumer video cameras that might have an IN-version of HDMI–mine has HDMI, but only OUT)?
This includes prosumer video cameras that might have HDMI inputs that you can use in VTR mode–my HD video camera has HDMI, but only OUTput. So what about those?
Also, what about any D-VHS that were made late enough to have HDMI INputs (not just the few with output-only HDMI)?
And if not, then why not?
Also, which satellite TV or digital cable TV receivers with DVRs have FireWire/iLink/IEEE 1394 OUTputs?
Hey, will you come back a little later and see my responses to your answers, please?
Thanks,

Yeah, Jettoblack, thanks, but I wasn’t talking about making an illegal copy of a Blu-ray disc; just recording and keeping HD from the air.
So what about recording and keeping HD from a TV signal past when the DVR fills up like we could do with standard definition, even in DIGITAL quality (if we hooked up a digital recorder like a DVD recorder or some digital video cameras that would accept input that way)?
Okay, so we can record SD in perfect or near-perfect quality by recording it from the air to a digital medium, so why not let us do that with HD (and keep it after the DVR is full)?
Also, if the media producers were going to try to prevent us from even recording HD TV to removable media, then why was D-VHS invented WITH a FireWire IN, AND why did earlier models of digital cable TV (and maybe digital satellite) tuners come with FireWire OUT so you could record HD video to D-VHS from those, AND why were D-VHS decks advertised with that very action as one of its purposes?
Also, Jettoblack, there already are TV tuners out there for computers that tune in HD and let you record those to your hard disk (which files you can then move to removable media), and those don’t need a special fast RAID to work. So somehow they must be compressing the video while recording, if we really do need the faster drive system for recording uncompressed HD. So it must not be too hard to have a CoDec or just hardware or combo. or whatever that can do that, but then I just need to get an HDMI capture card that can use that. Huh? But then if I could copy to D-VHS until Blu-ray recorders come down in price (if those even have HDMI inputs), that would be good.
So do Blu-ray recorders have HDMI in, then (for hooking to the tuners I was talking about), or not even those? And do Blu-ray recorders have their own ATSC tuners?
Jettoblack, will you follow up on my new questions here by editing your answer and adding your new comments below the original ones?
Thanks.

HDMI inputs are pretty rare. Some computer capture cards and video editing devices have them. These are only useful for capturing uncompressed digital video live from a prosumer HD video camera to a PC. (Professional cameras and capture systems use HD-SDI, which is a more robust digital interface). They won’t help you to capture TV or movie sources because those are sent encrypted.
To record from an HDMI input to a PC, in addition to the capture device, you need either a powerful codec chip that can compress HD video in real time, or you need a VERY fast RAID of hard drives to capture uncompressed HD.
Also, the media companies don’t want you to copy (and then be able to distribute) their works in perfect HD quality. They want you to shell out for the BluRay disc (preferably after you have also paid for the DVD version).

Edit:
The digital broadcasts via antenna/cable/satellite are already compressed to MPEG-2, which is why standard tuner boards don’t need fancy decoders or RAID discs, they just record the compressed data as-received. But HDMI doesn’t carry the compressed data, it carries encrypted but decompressed pixels (after they have been decompressed by the codec in the tuner/receiver box). So HDMI is not the way to go for this.
If you just want to capture OTA (antenna broadcast) TV, get a PC tuner card with ATSC (HD broadcast) recording capability. These can receive and record HD broadcasts (unless the “broadcast flag” is set by the broadcaster, which prohibits recording). Once the file has been recorded to your hard disk, you can use it to author a bluray disc. This won’t work for cable TV or satellite or fiber though, because they transmit all of their data encrypted and only the supplied tuner box can decrypt it (and the HDMI output from that will be encrypted as well).
As for your question as to why analog recording and D-VHS and such were allowed in the past but new systems have more encryption and prohibitions, I think Hollywood & the TV networks got paranoid after seeing how much internet piracy has exploded in the past few years, and after they saw how easily the DVD encryption was cracked. All the new formats like BluRay and HDMI have very strong encryption and restrictions now. If you don’t like it, don’t buy those products, or contact the studios and hardware vendors and tell them you want your freedoms back.
