do you mean those comb-like lines ???
these are normal for interlaced material and no error.
watch 'em on TV an they will be gone.
and i think the Media Player isn't the right instrument to have a look at the scripts.

That's probably pixelation due to crappy media, or the area where it was burnt has things like lint on it.

Hi XMEN3.

I had a very similar trouble on another movie. After some very astonishing checks, it turned out that the very first cell in the original title had a frame size of 702 x 576 (it was a PAL movie). All of the rest was originally mastered at 720 x 576. It was surprising to note that in these circumstances, the TRIM function, adopted by avisynth (and by DVD-RB for extracting the cells to encode from the origina movie) is producing always a 702 x 576 stream. If I am right, playing all of your avs scripts in your D2VAVS folder should generate the same type of artifacts, so it should turn out to you too is not an encoding problem...

Me solved the problem simply stripping out the first cell (that was an unwanted intro...) and verifying the artifacts disappeared BEFORE reencoding the whole...

Hope it help addressing the issue also in your case...

Very strange indeed this "funny" behaviour of the TRIM function...

Cheers,
SD

Edit: typed by mistake in many places 702... Of course it should be read as 704...

Multiple files loaded together in DVD2AVI/DGIndex must have the same resolution.

Sorry for my answer above.
I couldn't see the images in my office. I just read the text.

Mhhh, I see.
Thanks for clarifying this.

Maybe I am wrong, but picture resolution may change in any given VOB file (it is a property at the MPEG2 sequence level... right ?).

This implies that original DVDs like the one posted by XMEN3 (and the one I have, showing the same behaviour...) will be never properly decoded by DVD2AVI/DGIndex ? [and no straight backup of this type of DVD is possible using DVD-RB ?]...

Just for me to better understand the problem ...

... it is one VTS with different resolutions in the cells?

Or is it just the resolution 704x576?
There was someone else who had a problem with this resolution using DVD-RB.
