Now is this down to my friend, or a limitation of the XVID's resolution?
The second one. An XVID to DVD conversion is not a fair basis for evaluating the video quality. Grab one of the DVDs, they are flawless.
Secondly, could someone here also enlighten me if there so far has been just the XVID release, followed by ONE Pal DVD-5 release and ONE NTSC DVD-5 release, or have there been more?
There have been revisions.
Do these have more resolution than the XVID to give a PERFECT picture on a DVD?
Are these the ones with all the extras?
No, that will be the DVD-9, yet to be released.
I believe a dual-layer DVD-9 with even more is coming?
