Problems with jvc-drm100s. White lines at top of recording???

[mikej3131]

Hello i was watching one of my recordings from yesterday and noticed that in the end of the dvd i saw at the top of the screen there was white lines that looked like a bad vhs tape. What could have made this happen? I was recording off of a Comcast motorola dvr that i had recordings on. could this be timebase correction problems?

also, Can this recorder record some material in xp, then some more video in sp on the same dvd???? and if so, how would i do that and does it work with pausing or do i have to hit stop and make a new recording on the dvd to change settings?

Should i set IRE settings onthis recorder?

And is there anyway to dim this blue light on the front of this recorder????

1st para: that could be broadcaster's stuff that is usually hidden in overscan but may be visible when viewed on a pc or an LCD/plasma TV...could it be captions data (don't live in Us so don't konw for sure)...

2nd para: Of course it can mix recording modes, no prob, but in order to stop recording at all I think you need to press stop, pause won't cut it anyway...if you had already pressed STOP, of course you could change recording mode for the next rec session...

3rd: Yes there is the "dimmer" section in the "display set" menu with 4 options to dim the front display...

actually yes i was watching this on a computer.

1st para: that could be broadcaster's stuff that is usually hidden in overscan but may be visible when viewed on a pc or an LCD/plasma TV

So this stuff happens on lcd's???? is this onl;y when watching dvd recordings, or does this happen sometimes when watching tv from your cable box too on an lcd?

It happens when an LCD/Plasma have a low overscan ratio...usually people buy these for watching DVD films where you don't get this kind of stuff because DVD's don't come from broadcasts...what you saw may actually be broadcasted from an older/damaged tape because some broadcast machines (VHS too) if not properly maintained can distort the edges of VCR tape...how big in say percent of the picture height is the problem???...posting pictures of it may help

What is overscan ratio in non technical terms???? and if i get my tv and it has a bad overscan ratio , how will i know and can i set it to make it begtter?

You were viewing the overscan. And what you actually saw was the visual remnant of closed captioning data. It's hidden on a tv set, because of overscan (LCD panels almost always filter/crop overscan, at least the good ones), but a computer has no such concept.

The complete overscan is a range that varies from unit to unit, but on average is about the outer 7% of the image. The left and right are about twice as big as the top and bottom. Usually around 18 pixels worth of data on each side, and about 10 on top and bottom, when looking at an image in 720x480 rectangle pixels.

Never crop an overscan (you will distort the remaining image!) but simply mask it when needed. If you are converting from AVI to MPEG, it's a good idea. If you did an MPEG capture, just leave it alone, view on a device that can mask or crop overscan.

You definitely should recalibrate your display if you change from Standard, Cinema 1 or Cinema 2. The optimum settings listed are for each display mode, as calibrated using the AVIA calibration disc.

Cropping means zooming right? and if so, what about strecthing, would stretching be a good idea if my new 46 samsung coming in isnt able to get rid of this?

[lordsmurf]

No.

[mikej3131]

y?

[lordsmurf]

Distortion, aspect problems, interlace issues, you name it. Big pile of mess.

so if i have a bunch of 4:3 dvd's, and i am getting a new widescreen tv, i should never use the 16:9 mode????
