Official DVHSTool 2.1 Support Thread - Page 33  

post #961 of 1297
Rick: Is there some known compatibility issue with DVHSTool and the JVC 40000? It works pretty well, but there are brief pixelization issues and some sound dropouts in the recordings it makes to D-VHS (from single or multiple HiPix .ts files).

uzun,

I'm not sure. How many people are using the 40K? This is the first I've heard of problems with it.

Rick,

Thanks for posting. I thought i submitted this response last night, but I must have been punchy, because it's not in the thread.

As of last night, my newly refurbed JVC died (flashing tape error and shutdown). Yesterday when it was working, the Preview button was grayed out and I couldn't get preview to work at all. I previously had the window open, but it was like with the HiPix - no audio and no video.

Now, I'm thinking that maybe the problem had something to do with the JVC's failing status. I'll try again when I get the deck back. Thanks for the suggestions.

Welcome back. You were obviously missed.

I have a 40k. I tried using the 1394 card built into my motherboard (Asus A7V333) and the 1394 card built into my SB Audigy. The MB card worked a bit better. I have an Athlon XP 2400+, with 1GB of 266Mhz DDR memory, a 7200 RPM C: drive, and 2 7200 RPM drives configured in Raid0 as my D: running Windows XP Home. The .ts files are clean when I use VideoLan to play them back on my computer, but show pixelations and occasional sound drop outs when I transfer them to my JVC 40k. Even if I just transfer a single file, in its own directory I get brief pixelizations at irregular intervals. I wish I had another computer with 1394 I could try things on so I could see if that's the problem. CAPDVHS is much worse than DVHSTool in this regard on my system. I boosted the priority in the settings, and killed all non-necessary processes using task manager but that didn't help much. Is there some setting that might help? Like changing the timings in some way, or letting it send null packets or something like that?

What was the latest version of DVHS Tool?. Where can I download it since the website is down?

Thanks

I notice in your replies the "OAR is the only answer. All the content, all the time."

What is 'OAR" .. over the air record" ???

In fact where I live Richmond Virginia on the OTA stations I receive a rating of 5 to 8 and on one station a 3. The 3# rating is an interuption in signal every 5 mins.

Directv HD seldom a problem rate at 9 as I on occassion get a glitz / freeze of 1/8 to 1/4 second but does not impact enjoyment of novie. not every tape. In the "Two Towers" a 3 hour movie only 3 occurances.

Just interested what "OAR" stands for ??

Thanks

Regarding DVHSTool and the 40k problem. I had to replace my Motherboard, memory and CPU. I am now using a 2.6 Ghz P4 with an 800Mhz FSB and DDR400 RAM. The MB is an Asus P4P800 Deluxe which has built in Firewire. When I record to the 40k I get the same pixelization issues I did with the previous Athlon 2400+ setup.

So I think there's a compatibility problem with the JVC 40k and DVHSTool, or more likely with computer transfer to the JVC40k in general since CAPDVHS has the problem even worse. I will reformat the drive later this week and re-install Windows XP Pro (I use XP Home now), when I do that I'll try again.

uzun,

Don't know if this will help, but it works for me.

I have a 30k and I have to turn on and off the 30k four times before I can transfer with DVHSTool without dropouts. The symptom is that if I don't, the sound and picture drops out every couple of seconds while transferring. I don't know why turning on and off the 30k fixes it (Firewire or I number reset?), but it does. Does anybody else see this?
post #973 of 1297
Hmm.. so you are saying hook the whole thing up. Then while DVHSTool is running, but before I start the transfer cycle the 40k on and off a few times? Or just hook it to my computer, cycle it a few times, then start DVHSTool?
post #974 of 1297
I do it before I start DVHSTool. It's like a ritual that I have to perform for some reason, or else it fails for me. I turn on the 30k, turn it off, turn it on again, turn it off, turn it on again, turn it off, then turn it on and run DVHSTool and start the transfer. It's a pain in the ass, but it works! If I only cycle it two or three times, it doesn't work. I've tried restarting the computer, manually resetting the I number on the 30k, but only the recycling seems to work. This is with a new 30k (newer serial with the upgrade) using JVC D-VHS 300 tapes.

Anyways, good luck.

Because I find the fan noise objectional, I actually turn OFF the AC power to my JVC 30K when I am not using it! I read in another thread that this is very healthy for the JVC and am beginin to believe it! Why? Because I have NOT had any problems with my unit since November of 2001 when I bought it. In my HT system, I use a power distributor od the kind intended for PC's and have the JVC connected to one of the outlets in the back. When I want to use the JVC, I just turn on the AC power to it. NO fan noise and, so it seems, a healthy JVC 30K. Thanks for the attention!

I believe if you set the time on the clock or activate the 'power save mode', the fan will shut off when power is off.
post #977 of 1297
The fan doesn't run if you power down the 30k or 40k. You don't need to remove AC power from them, just turn the unit off using its on / off switch. I think the fan runs continuously only if you forget to set the clock on the unit.

Is the DVHSTool only available for Windows XP? Why? I have Win2K on
three computers and I am quite happy with it. Is there another tool,
that supports Win2K, that will allow me to hook my PC up to my
Mitsubishi HDTV and DVHS VCR?

Thanks,
Wayne

Welcome to the club, Wayne. The answers to your questions are:

Yes (in the sense that you mean from your final question).

Because (M$ wants it that way and no one else has taken up the challenge to write/adapt the necessary drivers to support AV/C devices under W2k).

Not AFAIK (and I did look pretty long and hard about a year ago).

So the solution to your problem is: Pay the ransom. :( Sorry.

Ricka and Leszek--
Has anyone actually gotten a JVC 30k deck to record hi-def at "normal" tape speed (vs. high speed)? I have tried to archive now at around 13mbps, and it still defaults to high-speed. What is the cutoff bitrate for the JVC to auto go to "normal" recording speed?

Thanks,
Spearse

I've recorded fox 480p stuff at STD speed. I think you need to get down to 12Mbps (overhead) or lower for this to work.

--Rick
post #982 of 1297
We are at 83MB/min = 11Mbps, but it still insists on recording at HS. Is there a way to force the JVC to switch to STD speed? This is satellite free-to-air DVB TS recordings.

Hmmm... The stuff I recorded as 8Mbps.

What's your peak rate? Remember that the constant rate sent to the deck will be equal to the peak rate found in the stream or the minimum rate configured in the registry - whichever is greater.

Leszek
post #985 of 1297
Hmmm... maybe I need to check the registry to see what the min rate is. What is the default settings for DVHStools?
Spearse
post #986 of 1297
See the following post couple of pages back in this thread.
post #987 of 1297
Thanks for the pointer Leszek. So StartupPacketInterval=2706 equates to 11.918 mbps, which is just under the magic rate where JVC switches to Hi-speed. I'm curious what's the harm in setting StartupPacketInterval to a much lower number? If you send DVHStools a .ts stream of 8mbps, will DVHStools need to stuff with nulls in order to satisfy a minimum required by the JVC (a speed of around 12mbps?)

Thanks
Spearse
post #988 of 1297
In theory there should be no harm in setting the number to a larger value (lower rate!). The only issue would be the first 1/10 of a second or so of the stream as the speed is adjusted to the peak rate. If you send a stream with a peak rate of 8mbps and the registry is set to 2706, then yes, you will get null packet stuffing so that the rate is a constant 11.918mbps.
post #989 of 1297
Thanks Leszek. I'll experiment with a higher value (lower rate) to see if I can coax the JVC to go to standard speed, but I suspect as you point out, it's already set to start at standard speed and bump up to hi-speed as it seeks peak rate.
Spearse
post #990 of 1297
I finally got the JVC to go into STD mode for recording, but I had to go all the way down to a 3.5Mbps transport stream to make it work. Anything above about 4 or 5, and it jumps into HS mode. I checked the stream with MPEGID and another program, and both confirmed the bit rate never goes above 7 or so, but the JVC insists on staying in HS mode. I wish there was a way for force STD mode, as I think the JVC is flawed or too conservative in it's setting to HS.
