Liteon 5001 - problem when recording from VHS

[snaimpally]

I have a late model Liteon 5001 which I got from Sam's Club. It has a built-in fan. Records well BUT ... when I record from VHS, often I get wavy lines at the top 1/16 of the screen. Its annoying because people's heads get very deformed looking. What can I do to fix this problem?

Does it look like this?

[snaimpally]

YES! That is exactly the problem. What causes it and how can I fix it?

[canadateck]

The only way I got rid of this (Short of using a TBC) Was Playing the VHS into another VHS PLayer and into the Recorder.

Panasonic ES10 sync filters would fix it most likely. Maybe a TBC in a JVC S-VHS unit. Any number of things. This is instability in the signal.

So this is a case where you expect the JVC TBC to "clean" the signal...

It's usually very minor and within the threshold of what these can do. Yes. It's a visible flaw.

The timebase error in canadateck's image is not "very minor"; it's quite substantial.

Isn't this what is known as a "skew" problem with the tape either being stretched, or the supply spool back-tension mis-adjusted??

Do you see this problem when you view the VCR directly to a TV?

Sure it's minor. A weaker line TBC or a simple sync filter fixes it. Doesn't even take effort to fix. Loop it through an ES10 or turn on the line TBC. Done.

Unless it's embedded, and then you're screwed. But if it's not seen on tv, it's not embedded, and can be removed.

That was my Posting about this Same Problem.


Like I said above Playing from one VCR into another and then Out to the Recorder worked.
Suffer quality? Didnt notice/didnt care. Was old VHS anyway.

TBC? Didnt use one.
I was happy with the quality in the end.

The video, when played on a TV, appears normal. It is only when I put it into the DVD recorder that I notice the problem. These are usually good quality recordings, e.g. 2nd gen copy of an off-the-air recording. That is, they are not poorly recorded or suffering from a weak signal.Interestingly, I have noticed that when I feed the signal into the front AV (analog RCA) inputs its less of a problem than the rear AV inputs.

I bought a little gizmo at Best Buy that allowed variable adjustment of the signal level and it did not solve this problem.

So if I got an outboard TBC, like a Datavideo TBC1000, will that solve the problem? What is the cheapest way to do TBC?

Thanks for your help.

I'll try that. I think I still have an old Mits VCR around.

Maybe overkill on my part however....

Since I have a ton of VHS and some Beta, Got rid of the U-Matic tho, I picked up a JVC 9911 S-VHS VCR, I've had S-VHS for many years. I use that along with a TBC, sometimes a Detailer and another device to adjust color and intensity. Note: I haven't needed the last two since I got the Pioneer 531h tho.

Moving on, the JVC is a miricle worker, It does a decent job on the signal it feeds into the TBC. The JVC was the only VCR I have tried that displayed a old homemade tape from 1980 in color, All the others gave a B & W picture... Very sharp but no color.

Since adding the JVC and the TBC I haven't seen any flagging in the picture and other problems caused by dropouts are cured by the TBC.

One other thing that may be doing overkill? If the original isn't DVD quality to start, IE VHS, DIVX, XVID QT, RM, Sat TV or Cable TV even then I give it all the help I can and also try not to squeeze more than 2 to 2.5 hours onto one disc.
