I have a day and night problem with my JVC D-VHS deck model 30000U. It used to play my small collection of pre-recorded HD JVC D-Movies and now it doesn't. However, in 2003 I taped HD OTA stuff in the high def mode via the Firewire connection between my Samsung STB and the JVC like the Oscars, the Grammies, the Masters cup, a PBS concert, and as recently as last month another PBS holiday special. THEY ALL PLAY JUST FINE back over the Firewire port, to the Samsung and then 1080i to my Mits. And when I try to play the JVC tapes, all tape handling and display indications are normal. I can FF, rewind, and when in play mode the tape counter is incrementing properly. It's happy. It "thinks" it's playing but no sound and no picture. Pop that tape out, put in the Grammies and voila - no problem.
I have two inquiries into the JVC website but no answer yet. Anybody have a clue?

It would be very helpful if you could verify if this is a 1394 problem or a problem with your VCR. Simply take the analog connections of your Samsung and move them to the JVC and try a D-Theater tape. If you have a picture then you will probably get sound using the VCR digital output connection.
Once you can verify this I can tell you what I think is going on.
If you still do not get picture/sound using the connections on the VCR then it is time for service.

In addition to what Richard mentioned above.....it sounds as if the firewire connection is working since it works with the tapes you have recorded. And I assume you are using the firewire conneciton when watching the pre-recorded D-VHS tapes, so try connecting the JVC 30k directly to the TV using the component outputs and the audio outputs of the JVC. Because you say the 1394 (firewire) works with one tape and not another I'm also wondering if the tape you recorded is in HD.
Just some other thoughts although I don't have a fix it sounds strange and I trust you have tried one than one D-VHS Pre-recorded tape. I say this since I had a bad tape and had to return it.

Yea, I could swap the component cables over. Richard suggested that offline before but I balked thinking it wouldn't tell me anything and that JVC should have the answer. The tapes I recorded are/should be HD. The JVC goes into "HS" record mode as soon as it sees the Samsung over the 1394 port. I'll let you know.

I have just now moved my component cables from the output of the Samsung T165 (feeding the 1080i Mits input) to the component outputs of the JVC 30K and I have picture - no problem with all three JVC D-Theater tapes and no problem with the HD recordings I made in HS mode recorded OTA last year via the 1394 link between the Samsung and the JVC. Everything plays now.
So. What does this mean?
Self-recorded tapes play over the 1394 link but not the D-Theater tapes. But both play out of the analog YPbPr connection.
Any clues would be appreciated or just link me. I spoke to a JVC customer service guy at JVC today but he admitted he was clueless (but also asked whether I had tried the above) and said a more 30K-savvy tech would call Monday so we'll see.
Jim
PS
Hugh, I'm sorry I upset you and others recently. I am clueless as to where I was at that night. Happy Super Bowl

Thank you for checking on that. It appears someplace somewhere your 1394 is being turned off by D-Theater encoding. When this deck first came out I was quite shocked that this was allowed, D-Theater with 1394. It would appear that either your STB or VCR has had some software upgrade downloaded during normal use. I suspect the download came off a tape.
BTW, this kind of update happens all the time with satellite STBs.
Jim, please list all D-theater tapes. Have you checked AVS for this problem?
Hugh, Since you have the same rig it would be helpful if you could confirm your D-theater tapes work via 1394. You have at least one don't you?

My stuff works ok, but I bet it is a problem with the Samsung. There is no way the 165 or the JVC 30K could have had anything down loaded since it's not connected to anything other than an outside antenna. My movies work through the 1394 connection .... both D-VHS and ones I record. The Samsung has some intermittent quirks and the JVC has also acted up playing back tapes I recorded.
Jim, you might try posting this on Tips and see if anyone over there has any knowledge of a similar problem. Quite frankly I would never be surprised at anything the 165 or the 30k did or didn't do properly. The software in the 165 definitely has some issues and the transport system in the 30k is not the best in my opinion.

Richard, I don't recall exactly when I got U571 but it was sometime after you got yours because you told me it was excellent viewing, etc.
Yes, the T165 just gets lost sometimes but I have power cleared them both, first one then the other, then the other then the first, and so on, to no avail. And the home made tapes always play.
Still haven't heard back from JVC today.

Right you are! Samsung used to offer Starsight menuing systems on their VCR's and all of the information used to update the system was transmitted as a part of the NTSC PBS broadcasts. You could receive it OTA or over cable/sat, and needless to say that was analog.

Yes, I posted the problem to AVS two nights ago and already have several responses. Two said they had the same problem. One indicated JVC upgraded him to a model 40K but didn't elaborate and the other indicated it was his T165 and needed a firmware upgrade but didn't elaborate. My response was to ask for clarification. What actually got fixed and why would things be fine for my set-up in fall 2002/winter 2003 and now it's broke, etc. I think I should rattle Samsung's cage as well. No news from JVC tech support but I have a number I keep calling.

There are a significant number of people out there who shelled out big bucks for the much hyped JVC 30000 D-VHS player and can not, or could and now can not, play the hi $, JVC mastered D-Theater tapes they bought. This is not good for the future of HDTV. D-Theater is the only source of HD viewing some countries have - and their JVC players no longer or never did play them reliably.
We need an international lawyer. Class action suit against JVC. Recall. I've read enough. JVC has a large problem - either with their player or with those manufacturers they partnered with (Samsung) to be able to play JVC mastered D-Theater tapes over the digital Ilink/firewire/IEC1394 connection. The analog outs from the JVC 30000 playing D-Theater also have problems. It's very confusing out there. But the common denominator is the playback of JVC's own self- mastered D-Theater tapes. People all over the world have invested in this deck, and a library of D-Theater tapes and after a time they no longer play - and/or there are many variations to the theme. There are many arcane solutions out there but the common thread is D-Theater tapes. If you record something in HiDef in HS mode on your deck it's going to be fine. Pull that tape out and put in a $40 JVC D-Theater tape and you are met with black screen and silence. Day vs night.
Got this problem? Got this name and number from a fellow sufferer on AVS:
Call Marek Wolynier 973-317-5000 JVC contact.

I'm very sorry if my last posting was a "thread-stopper" but I am p/o'ed a bit. I am interested in/push/involve others in HDTV but really do not like owning, and reading extensively about others owning, a hi-$ "lemon" HDTV product. JVC 30K
