D-VHS Recording in 2018

For fun sake trying to print some MPEG-2 videos to D-VHS JVC HM-DH5U using a blank D-VHS tape, But I couldn't get the deck to start recording using CapDVHS in write mode, I could capture non copyrighted D-VHS and VHS tapes using either CapDVHS or VLC but not the other way around, I couldn't find other applications to try like DVHStool, All links are dead.
Oh, I tried both Windows XP and 7 64bit, neither worked
Both laptop and D-VHS deck communicate and recognize their names.
Here is the file info:

If the transport won't start moving this may not be your problem. I think that the DVHS machines need a file with a constant data rate. If you can record the complete stream from an ATSC TV station you will have what is needed otherwise I think you can make a constant data rate file by using VideoReDo by playing around with their zero padding option.

I would think if a file type problem I get an error message, But the deck doesn't seem to respond at all when I hit start on the CapDVHS program. I even put the machine to record from firewire and it does display Sony which is the brand of my laptop but nothing worked, machine records black video, So it's clearly a windows/capDVHS problem.

Keep in mind the file I'm using was a stream from DN with a moded 6000 receiver, Those files suppose to be ready to be recorded into any D-VHS machine using DiscToTape app from nextcomwireless which I used and it gives me a DVR communication error message.

im curious you can record in 1080?


i just search about d-vhs , created in 1998 but short life because dvd appears, looks rare honestly you can check videohelp or digitalfaq i guess.

Problem solved!

First, The recording to a firewire device can only happen in Windows XP for whatever reason, Windows 7 cannot detect a firewire recording device, It can capture from firewire with no problems.
Second, The file has to be transport stream with a constant video bitrate.

I dug out one of my old hard drives and found a copy of DVHStool app.

Both CapDVHS and DVHSTool worked with no flaws, However, DVHSTool have the capability to control the tape transport, Record/Stop, Can record multiple files in sequence and creates a blank leader at the start of the tape before it starts laying down the data, While CapDVHS only streams the data, you have to manually put the machine in record before you send the video file and stop at the end of the file, Not ideal if you are not around the machine.

Hi guys, I am also one of those who still not only use it for playback but records on D-VHS. I have two HM-DT100u decks, they allow also to capture HD via built in ATSC tuner. Years ago I spent lots of time trying to record from PC to DVHS via FireWire. I even got my old PC with Win XP working with all the DVHS Capture software installed. It all worked, the major problem was access to properly encoded TS video files which DVHS would capture. That was a real challenge as I was unable to find any software package which would produce such file.
The only way I could test the recording to DVHS deck was to capture some HD show from antenna, that records on tape just fine. Then import it to PC via firewire, it would produce constant bitrate TS file. Then I try to send this file back to DVHS deck via FireWire recording it on tape, it worked flawlessly.
But none of the software tools, and I mean I checked handful of these to produce. TS file with valid stream that would get recorded without drops into the tape.

So after a year of research and unsuccessful trials, I started to look for ATSC/QAM modulators. Entry level cheap modulators with no virtual channel capability were not allowing DVHS tuner to catch programs properly. I had to use prosumer modulator to make it work. And since then, I could finally use DVHS to archive my recordings.I can even create dvhs tapes with 5.1 multichannel sound encoded in AC3 as modulator I use has multiple digital video and audio inputs so you can mux to whatever format or audio and video combination you want. The result is ATSC stream that perfectly fits DVHS deck requirement for clean and smooth recording.

But I still feel I missed something back with my FireWire experiments. And I wish I could find the way to convert raw MPEG-2 stream into TS format acceptable by my DVHS deck. One limitation of recording via modulator is that max total video and audio bitrate in ATSC standard is 19.3Mbps while DVHS deck is capable recording up to 28.2Mbps which is way more and should producer even more crystal clear tape recordings with less compression. There is also QAM supported by modulator with up to 38Mbps and for my DVHS deck the modulator would need to cap it to 28Mbps. But I have not tried this option yet.

So if anyone has successful experience with creating dvhs valid TS streams on PC and recordings these into DVHS tape, I would appreciate pointers.

The Windows device driver for detecting DVHS hardware only works on 32-bit Windows. 64-bit Windows drivers do not exist. I have used the 32-bit DVHS drivers with Windows 8.1 and an early version of Windows 10. Windows 7 can be a pain in the ass because it has seriously screwed up Firewire support, but you can have it switch to using the "legacy" Firewire driver.

Do you mind showing me how to do that? Thanks

Hi guys,

Getting back into DVHS after a break. Wasn't there a user who reported either windows 7 or 8 x64 auto updated drivers for a DVHS deck a while back?

Does anyone know if windows 8 drivers work in windows 10? I thought the driver model was backwards compatible meaning new WDM driver versions are super sets of older versions.

I am going to recompile the Microsoft DVHS sample app tonight on my Hades Canyon system. I hope VS2017 doesnt choke on the old c++ from 15 years ago..... Wonder if it will even run on 10?

So what is the best way to transfer d-vhs recordings from tape to PC hard drive?

I hope that we will soon try coping a 1080i MPEG-2 CBR 29.976fps ts file (converted from 1080p AVC VBR 23.976fps m2ts file with Rhozet Carbon Coder).

Do you have access to Rhozet Carbon Coder? I bet it's an expensive software.

Have you tried TSReader Pro to produce a padded TS file for transfer to DVHS through software such as the OnAir Tuner software which had DVHS transfer capabilities?

I use CapDVHS, But you can only transfer non protected analog and digital tapes, the deck will not send a D-Theater signal through firewire and it will not digitize an analog tape with Macrovision.
