whats the best way to put svcd files onto a dvd, do i need to convert them or can i just burn them into vob files??

The best way ? Read a little the forum and/or make a search.

And also the best way depends finally on the Standalone Player model as its not guaranteed that it will be supported!

Depends on how you define "best".

If best = easiest,
get Roxio WinOnCD 6 DVD Edition (often you get this as bundle with your DVDR drive, where I live), which will accept 480x480 / 480x576 resolution video, put it into vobs and burn it as nice non-standard-DVD.
I've tested this on one standalone so far, and it worked.

If best = DVD-standard with least quality loss
do a multi-pass reencode to 720x480/576 with same aspect ratio flags, and bitrate as high as possible (still <= 8000kbit), to use the full capacity of your DVD. (I guess you want several SVCDs to 1 DVD?)
Demux the audio, do a 2-pass upsampling from 44100 to 48000 Hz using Besweet's SSRC options.
Now author the files individually using IFOedit or DVD Maestro or whatever you got.

If best = DVD-standard, fastest
do as above, but only single-pass

I guess that will do it.

Why "multi-pass" ? CQ mode will always be better and faster (or Q mode if you are using CCE). Needs file size prediction but we are used to it with KVCD yet.

AFAIK Multipass is better than OPV on CCE because of vbr_bias.

AFAITME (ie As Far As I Tust My Eyes) : No.

Or perhaps after the 3th pass, but I don't really have such time to waste to obtain the same result I can have in one shot.

Well I see clear difference between OPV and 4-pass, since I'm doing only high quality DVDs I don't care about time I have plenty.

I still do OPV only on non-DVD source

@ Phil and Lagoon :

a long time ago i did "shrek" using 5 passes,
(yes,...5)
my pc was k6II-500-128mbram.
was needed more than 20 hours only to encode the video with cce265.

the result is amazing for 2 cdr-700mb!

now i use only tmpgenc(for mpeg1 and/or mpeg2)!
with the Kwag's matrix and best script,
the result is fantastic for only one cdr 700mb!
.....and faster than cce 5 passes!

Well I use CCE with KDVD matrix so it's the same.

It's known CCE is a better and faster MPEG2 encoding tool than TMPEG.

4 passes takes about 2h30 on my P4 2.8 @ 3.5 so time isn't a real issue.
