Pros Allows Recording of HD Programs via fire wire
Cons It's still tape.
Summary The JVC HM-DH30000U does everything it was advertised to do. It was the first machine available that allowed video consumers to be able to record HD programming via i-link input from either an HD off-air tuner, a digital cable or satellite receiver. It also happens to be backward compatible to record & playback regular VHS and SVHS tapes. DVHS is now in it's third generation after the HM-DH40000U (incorporated DTS) and current HM-DH5U (adds HDMI out). No other machines available today can make a permenant, portable recording of HD programming and you probably won't see any others that will for a few more years. Try even finding a DVD recorder for consumers that can record HD (they don't exsist yet and won't for several years). You can pay a high extra fee every month to your cable or satellite provider to rent an HD capable DVR or spend much more than $500 to buy one. But what happens if it fails? If you rent the DVR and you decide to move or change service providers what happens then? You loose all of your recordings that what! For recording HD programming it's the right machine! I wish the DVHS blank tape were a little less expensive because I have recorded so much HD material off-air and from Dish.

Pros Picture quality and MPEG conversion
Cons Uses tapes
Summary It isn't true that one cannot connect the unit to a computer. There are at least two ways to do so with free programs (DVHS tool and CAPDVHS). One can record from the units' video inputs into 3 different MPEG resolutions via ILINK to the computer (although I have not been able to record directly from an ILINK input, i.e. DV, to the computer - need to record to DVHS tape first). VHS and SVHS tapes played on this unit will NOT output to the ILINK port (there is obviously no realtime analog to digital conversion when playing analog tapes). The ILINK output is compatible with VLC.
Unit is now obsolete, but I found one for around $100. Will play S-VHS, VHS and D-VHS with incredible quality. I wanted to use it to convert my personal VHS and S-VHS recordings to MPEG, but only DVHS tapes will output to ILINK. However, using another VCR connected to the SVideo and audio inputs allows for real-time MPEG encoding. One can also archive DV input to DVHS tapes.
All in all, a good idea for its time - unfortunately, the format did not survive. High bitrate DVHS quality is higher than DVD.
Pros Supports HD
Cons Doesn't talk through FireWire to computer - no way. JVC tech support bounced me back and forth, finally said "it's software problem". I've tried four different software pieces: Adobe Premiere Pro 1.5, Ulead MediaStudio Pro 7.01, Windows Movie Maker 2, Mai
Pros The only current way to record HDTV content that uses the 'Copy Once' broadcast copy protection system. You can use it to archive and save ANY HD broadcasts that are available through your HD reciever (your reciever or cable box must have an active 1394
Cons Tapes are not the preferred method of recording, but when it comes to storing huge amounts of data (we're talking about 60-70 Gigabytes), these tapes are simple and effective, but are prone to deterioration over time from the contact with the playhead. T
Pros Plays HDTV through component video and DV (firewire) connector, but records HDTV only through DV connector.
Cons Virtually no selection of HDTV movies after 2 years. Has no component video inputs. Cannot record standard signals digitally. That is, does not really do bit stream recording nor does it record standard programming digitally. For this it's just a plain ol
