Video inteference in captures, but not in output

[vulcan4d]

I just got my new capture card, the Kworld Dvd Maker. Anyway I hooked it up through S-Video and noticed the picture to have some signal interference in it or something. There are diagonal lines in constant motion, really easy to see. I found it odd I got interference since it is a high quality S-Video cable, and displaying my PC output on my TV produces a perfectly clean picture when using the same cable. So why is it clean one way, but not the other? I thought it was the capture card until I hooked up my dvd/satelite receiver closer to the computer, 6ft, and the picture was perfect. The S-Vidoe cable I use is 25ft but it is high grade. I would normally blame it on the length, yet I don't get why PC->TV is clean and yet DVD/SAT->PC has serious interference.

Any ideas why that is?

What you are seeing is interlace lines which is normal and looks crappy on a computer monitor which displays progressive scan where as tv use interlaced display,once put back onto dvd-/+r the picture will look normal played back on your dvd player on your tv.

No, no, they are not interlaced lines. Interlaced lines show up horizontally, these show up diagonally. Let me give an example.
I hooked up my dvd player for best video quality via my 25ft high grade cable and captured a photo.



Looks like utter crap doesn't it? Hooking it up via a crummy 6ft cable shows a perfect capture. As I said earlier, what really puzzles me is why the picture is perfect if I hook up my PC to my TV via the same 25ft cable, I mean it's crystal clear..umm for TV that is lol. Could it be that the output from my ATI 8500 is amplified to prevent signal degradation, and the output from my satellite/dvd player is not resulting in crummy captures?

Seems to be interference in the capture card itself,are the lines there for direct tv capture as well as any source input?

My Sci-Fi channel on cable looks like that except it doesn't look too bad on the TV but the capture process (probably the fact that you are looking at it on a PC MONITOR) makes it look more bad.

I think it is the PC MONITOR that is making it look "worse" because of the increased quality of it (PC MONITOR) bringing out more detail ... or junk ... in this case.

So chances are once burned on a DVD and played back on your TV it will look OK again.

In other words ... it's there even on the TV ... it just isn't as noticeable on your TV as on a PC MONITOR.
