[SOLVED] VCR / VHS to PC Corrupted Line Bottom Part of Screen & white background noise hiss

[retroborg]

Good day

I have a VCR Sharp VC-90ET & Hitachi VT-498EM Tape Recorders connected to my PC using a Leadtek Winfast PVR3000 Deluxe hardware MPEG capture card via an RCA A/V cable. Both seem to work fine with an exception of:

1. A horizontal corrupted line on the bottom part of the screen as pictured in the these YouTube videos. It is more pronounced on the Sharp and slightly more transparent on the Hitachi.

2. Also when I play a VHS tape and capture / convert it into an mpeg file, I can hear a slight background white noise like a constant hiss if I increase the volume of the PC speakers higher than 30% when I play the mpeg. The noise is slightly higher when using the Hitachi VCR.
This occurs with every single VHS tape I've tried and are all in great condition, thus the problem in probably not within the tapes themselves. I also tried a another PVR capture card with the same results.

So is this some technical problem with the VCR recorders and can it be fixed? Maybe cleaning?

My setup:

Intel Core 2 Quad Q9500 @2.83GHZ
MSI GeForce 1070 8GB Gaming X
Creative SB X-Fi
8GB Ram
256GB Samsung SSD 850 PRO
Win 7 PRO 64BIT
Nvidia Drivers 441.87 English
Leadtek Winfast PVR3000 Deluxe hardware MPEG

Thanks in advance

Hi retroborg , i had this happen many years ago and never found out why but i do have a tip for you.
DONT watch anything on the internet whilst you are transferring your video tapes etc to your pc.
My son did some vhs to pc copying and he decided to kill time by watching porn on the internet whilst doing the copying.
The end result was that he had the correct video BUT the transfer set up somehow picked up the sound of the porn and overwrote what should have been the film sound.
Dont ask me how it happened all i know is that it did.

Does the line show up in a TV as well? Seems just like a tracking issue. VHS Is not the best format for quality, tapes and players get dirty, wear out, stretch, rollers dry out, tracking goes out of alignment.

This line has to do with how the signal works, depending on format it can show up in the bottom on top or on the side.On the TVs of the time it would have been outside of the viewable area of the screen.
Tracking issues would be much larger and all over the place.
My guess would be that you are seeing the Vertical sync line as described here.

For the noise you most probably have some issue with grounding, the shielding of the sound plugs isn't connecting or somewhere there is an audio filter (internal electronics) that isn't working that well anymore.
