Panasonic EZ48 combi - copying query

Just bought a Panasonic EZ48VEBK VCR/DVD combi player/recorder - works great .........

A minor issue though - if I copy a tape to a DVD-R then no problem, I finalise it and it plays back on the player. All looks fine, seems to be a perfect copy of the original tape.

However, if I pop the newly burned DVD-R into a PC and play it back there - again, it plays back, BUT there appears to be a few extra lines of image data (perfectly valid data, just distorted) at the very bottom of the screen. These extra lines are definitely NOT visible on the TV, irrespective of the aspect ratio selected (the TV is a Widescreen and the TV and Panasonic combi are both set to Widescreen - the source material was recorded in 4:3 on a 10 year old JVC camcorder but the manual states that:

"The original aspect used for the source programme will also be used with the recording."

This 'extra' data that I'm seeing is slightly distorted left/right and has a more visible bright line at the top of the area.

It's definitely NOT visible on the combi and TV - if I pause the DVD-R at a point where I can see how much screen 'height' is taken up by an object then on the TV I see slightly less of the image than when played back on a PC.

I've tried two PCs and assorted copies from/to different tapes/DVD-Rs, same results whatever.

Any ideas please as to the cause of this issue? It's no big deal but I'm wondering if it's 'normal', a setting that I need to adjust on the combi or maybe even a fault with the unit.

It is entirely normal.

The effect is as a result of the tape head entering the scan of the tape ribbon at the top of the screen and the head switching point from one head to the other at the bottom of the picture.

These are always present on helically scanned video tape recordings but traditionally are not visible due to overscanning which has been a normal feature of TV's.


Some software such as TMPGEnc can put masks over these areas, adjustable on a line by line basis... but it would mean re-encoding the material again, which is undesirable from the point of view of loss... both in quality and time spent.
