I finally bought and tested Hitachi HD D-DVHS DT-DR20000.
It's great machine. Look great and sound great.
It has two IEEE 1394 port ( i-link ) and record analog NTSC signal.
I can't tell any difference between original and copy . source was LD)
Funny thing is that it says 'Copy protected " to analog DVD input regardless of Macrovision.
( all Hollywood major DVDs are copy protected. some minor DVDs are OK. )
My dvd player is macro freed.
It can record any MPEG2 Transport Stream data . So it works perfectly with Panny TU-DST 50/51 .( Japanese AV magazine 'HI VI' confirm this .)
It has component input ( only pass through mode) and component output.
it records audio as MPEG-1 layer2 mode from analog source.
price would be 1800 - 2000 USD same as MV-DHE10 ( current production).
JVC and Toshiba model will be 200 $ higher.
I posted before , but erased mistakenly.
JVC will produce HD capable D-VHS machina HM-DH30000 coming December for Japanese domestic market. http://www.victor.co.jp/products/vcr/HM-DH30000.html
Interesting feature is
Built in MPEG-2 decoder, self play HD from D-VHS without help from settop box .
It has component output ( Japanese unique "D" type port : there is cable for normal 3 pin ) and optical digital output which can send AC-3, AAC, PCM.
( It's really nice to send out Dolby Digital AC-3 signal, which is very important for USA and Korean consumer )
Direct input and recording from DV-camcoder using IEEE 1394 port.
I can link panasonic TU-DST50/51 settop box without any problem.
Toshiba also released news of their first HD D-VHS machine .( I guess it's OEM of JVC)
All Japan made settopbox and D-VHS are compatible through IEEE1394 link
