I've read through half the thread but haven't seen this issue mentioned:

I can play back a TS file from my computer to my JVC 4k via Firewire using the current version of dvhstool fine. Watching the output of the JVC during the process, I see an occasional glitch that I think was part of the ts recording all along.

However, if I record the program on the JVC, and watch the tape, later, there are MANY more glitches than what I saw while monitoring it. The glitches are like pixelation at various places, not stuttering or jerkiness or anything like that.

I have done the typical things, like making sure the tape is okay by recording direct from the cable box via Firewire. I have subjected the TS file to mpeg2repair -- and though some of my ts files have glitches, even a file that mpeg2repair says is 100% okay still has the same issues.

Maybe this is something easy for me to fix?
post #1265 of 1297
Couple of things:

1) Are you using the latest TSP2SP filter? (The one from July 2003, version 1.1.7.8.2003) It comes with DVHSTool 2.2B1. The 2.1 version of DVHSTool has a version that might create dropouts.

2) Are you using high quality tapes that have not been previously used?
post #1266 of 1297
I must have the older version of the TSP filter because it's the default one that is installed with the DVHSTool version 2.13.

Sounds like I should install the beta version of the tool, to get the newer filter, and then perhaps downrev to 2.13 (by running that installer again?) if the beta proves unstable?

Regarding tape: happens with brand new D-VHS tape (Mitsubishi brand) and with Fuji S-VHS.

I'd really think it's something with my configuration -- because so many people don't seem to have the issue -- but I'm running with all default settings. Would it matter which preview filters I've selected? Those don't come into play if I'm not watching anything on the PC itself, right?
post #1267 of 1297
Yes, tapes are brand new. I tried CAPDVHS and have the same problem, can record to HD but not to tape.
Don't know about filters, both CAP and TOOL were downloaded just a week or so ago

Wonder if I have to specify a path? And I don't know if the settings I use for either program are correct.
I searched all over the place and there are really no idiot proof instructions to use either program.
DVHS HOWTO helped in setting up the connection and installing the drivers but is no help, at least to me, in running either program.
When playing from HD, sound and video are ok, no stuttering etc.
Thanks for the reply.

post #1268 of 1297
I knew it was something STUPID !!
I did not use the channel selector buttons on the JVC to select Ilink=firewire for recording.

Works fine now, both directions.
Thanks for your help

Wow, okay, so the BETA version really helped things. Errors in the TS file that would cause a problem during monitoring of dumping a file from the computer to the JVC 4k are smooth now. There is still the occasional pixelization that ONLY is visible on a tape, after recording (but not in the transport stream as I am watching it WHILE recording) that does not appear to be tape-related. But more testing will tell me whether it is consistent, or frequent enough to worry me.

I'll take further discussion to the BETA thread (unless there's another response here).

Thanks!
post #1270 of 1297
Occasional pixelization that is not consistent usually is caused by dirty heads.
post #1271 of 1297
Thanks for the additional troubleshooting suggestion.

Yeah, dirty heads is what I thought, 'cause in the DAT world this kind of thing was always the sign it was past time to clean the heads. However, cleaning and a new tape didn't solve it. In fact:

In this situation, if I record direct from the cable box Firewire ouput to the JVC4k, what I see while recording is what I get when playing back the tape -- NO occasional pixelization. So there's something more subtle, I think, going on....

HOWEVER, the "not consistent" part of your statement made me think... and, I think that it is often in the SAME PLACE on the tape, often near the same place in the image -- so I still think there may be glitches in my TS file on my PC that for some reason don't cause a problem when using DVHSTOOL -> JVC -> Projector but DO cause a problem when using DHVCSTOOL -> JVC -> tape then tape playback via the JVC -> projector.

---

Question: In reading through the BETA thread, there is mention of going here:

http://www.webtc.com/DVHS/default.htm

and grabbing this filter:

http://www.webtc.com/DVHS/TSPFlt.zip

and following the steps here:

http://www.webtc.com/DVHS/default.ht...20video%20tape

Is this worth trying, as well? The person recommending it mentions that this was his solution to some minor pixelization....

but I have not yet finished reading through that thread, so maybe I'm missing something....

That web page was written by me more than 2 years ago. You will not get a good performance out of that very, very old filter. :) What you can try is what Robert (user: robena) did for his newer 5U deck - increase the minimum rate to that of ATSC. See one page back in the thread.

Yes, you can set HKEY_LOCAL_MACHINE\\Software\\DVHS\\TSP2SP\\StartupPacketInt erval to 1826, to have the bit rate set to 19.3 Mb/s.

The glitches can also happen if the TS file is not constant bit-rate, but variable bit-rate.

In that case, use TStoATSC.

That does not always work, some streams are really reluctant to be dumped to tape, and need a full remux.

And some streams remain glitchy even after a full remux...
post #1274 of 1297
Cool. Thanks, guys. Changing that registry setting appears to have cleared up that final occasional problem. A few more successful transfers to tape and I'll feel confident, but so far, everything looks better.

But I changed the registry setting (HKLM\\Software\\DVHS\\TSP2SP\\StartupPacketInterval) to 1684 -- as the earlier posting (also from Robert) indicated. Is 1826 better?

(I've got TStoATSC but it turns out I've never needed to move beyond MPEG2Repair in terms of fixing a TS file.)

I had once a file that worked better with 1826, and I used this value since without further problems.
post #1276 of 1297
Interesting. I'll keep this alternate value in mind. But only one of these (1684 or 1826) actually corresponds to the ATSC rate for 1080i, right?

Now that I write that, I realize I've only tested 1684 on 720p material. Does it matter?
post #1277 of 1297
well, rate = 35250/interval, so for 1684 we get 20.9Mb/sec and for 1826 we get 19.3MB/sec. The 1826 setting is closer to ATSC rate. Resolution does not matter. What might matter is the rate hint embeded in the stream which is usually very out of whack. :)

1826 is ATSC 19.3 Mb/s.

It should not matter if it's 720p or 1080i.

I'm a newbie trying to install DVHSTool. I'm not even able to install AV/C Tape Recorder/Player driver. After connecting from JVC 40k to computer via firewire, only the AV/C Tuner found new hardware window comes up. According to How To, both should come up. Of course, I cancel the AV/C tuner driver, again as per How To. Still, no AV/C Tape Recorder/Player driver hardware found. Looking for someone to guide me past this.

By the way, I'm running Windows XP Service Pack 2.

Thanks,
post #1280 of 1297
It could be that Service Pack 2 automatically identified your DVHS deck and installed the driver for you. Ensure that the deck is connected and turned on and see in device manager if you have it already there.
post #1281 of 1297
leszek1,

Thanks. It was already in device manager. It is designated as Device type:Sound, video and game controllers (which is what I expected and should be.) But, is listed as Manufacturer:Generic (instead of what I would have expected as JVC.) I'm hoping this doesn't matter. Also, designated as Location: AV/C Multifunction Device. The main thing is that Device status sez that This device is working properly.

I suppose I'll go ahead now and download DVHSTool.
post #1282 of 1297
johnnynuke,

With SP2, I believe that you need to manually update the device driver under "Sound, video and game controllers" to be a "JVC Tape Device" in order to get DVHSTool to work.

WHat do I need to do to fix an audio sync problem. Starting about 5 minutes into a transfer to my dvhs it is marginally off with the audio sync, but after an hour or so it is more than a second or 2.

With many streams, the JVC audio decoder drifts slowly.

Typing Pause/Play (while playing, not recording of course!) restores lip-sync.
post #1285 of 1297
Can someone here help this DVHSTool newbie? I followed the installation instructions to the "T" but DVHSTool only gives me a "No VCR" or "VCR Off, No Tape" message in the lower right hand corner even though it's on and playing. I have my equipment daisy-chained in this order by firewire.

Mits 52525 TV <--> Mits HD2000U DVCR <--> SA3250HD STB <--> PC

I installed DVHSTool version 2.20b1 on my XP SP1 computer and then followed the procedure to install the driver for the DVCR as described. Eight bubbles popped up saying new devices found. I cancelled all until the AV/C Recorder appeared and proceeded to install the JVC Tape Device driver. All seemed fine, but no matter what I do I cannot get the program to work. I double checked to see if my PC is seeing the DVCR by removing it from the firewire string. As expected, the JVC Tape and AV/C Tuner devices disappeared from Device Manager. With the DVCR connected, DVHSTool is seeing it because I see it listed by model number in the Active VCR drop down menu under D-VHS/Settings, and it goes away when the DVCR is removed from firewire. I still get the "No VCR" on the bottom and clicking "Restore" from a folder in the left pane produces no action.

Any thoughts? It's probably something really simple that I've overlooked, but I've been looking at it too long now and need some suggestion from the experts.

Thanks

David

Although originally designed for a 169Time modified sat receiver, DVHSTool v2.2 may well work with your configuration. Install the JVC Tape Device twice, once for the tape deck, then again for the cable receiver. DVHSTool General Settings should show both devices in the Active VCR pull down menu. Check the Control Tape Transport box, close the program and reopen (this may be the key step). If you have connected the firewire chain correctly the control buttons should now be available.
post #1287 of 1297
OK, in Device Manager there are 8 uninstalled 'devices'. 2 AV/C Tuner, 1 AV/C Panel, 1 AV/C Monitor and 4 Unknown Devices. With the monitor disconnected, only 1 AV/C Tuner, 1 AV/C Panel and 2 Unknown Devices show. Which one of these would I need to install with the JVC Tape Device driver for the STB?

BTW, I connected the DVCR directly to the PC, bypassing the STB, and got the same results. Also, when I start the DVHSTool program my DVCR automatically turns on, yet it still shows 'VCR Off' on the bottom.

post #1288 of 1297
Remove the TV from the firewire chain, uninstall DVHSTool, then reinstall. Then daisy chain the deck with STB and plug into your computer. You should here the tones as XP recognizes the devices. When manually entering the JVC Tape Device per DVHSTool setup instructions, do it twice, one for the deck, one for the STB. You should then be able to verify what devices were installed on the Active VCR pull down menu.

The TV in the chain may be confusing the setup procedure. Before reconnecting the TV, in Device Manager, Sound, video, and game controllers, you should have two AV/C Tape Device lines. Right click on each and navigate to Properties Details for verification of your STB and deck type.

Then reconnect your TV. If nothing seems to follow as stated, DVHSTool may not be compatible.

Bob,

The 169Time receiver emulates a tape device. All cable boxes expose a tuner device. You will not be able to install a tape driver for a tuner device, no matter how hard you try.

post #1290 of 1297
Thanks Bob

I finally got it working. When first installed, the connection between DVHSTool and the DVCR wasn't working correctly when the STB was positioned between the two. I got it working by uninstalling DVHSTool, connecting only the DVCR to the computer, then reinstalling DVHSTool. It worked after closing, then restarting the program. I then reconnected the TV and the STB to the firewire chain and it still *seems* to work. I have yet to play back anything, but at least I'm getting something to the hard drive. My intention is to only archive from the DVCR, not the STB.

Thanks again.

David
