MPEG1 or MPEG2 when creating a XVCD/XSVCD

[Teleport]

OK.

Definitions of XVCD and XSVCD
https://www.videohelp.com/xvcd.htm

I have been encoding XVCDs as described here
https://www.videohelp.com/tmpgencxvcd.htm

According to the first link (and the glossary on this site) the only difference between using XVCD(MPEG1) and XSVCD(MPEG2) is resolution (Both have data rates of 1.5Mb/s). But I have been using higher resolutions than standard XVCD anyway using the guide in the second link above.

So...

Instead of just following the guide and leaving the stream type as MPEG1 in the settings tab, I change this to MPEG2 encode the file and then use the header trick...

effectivly creating an XSVCD which fools my player into thinking it's a VCD.

Here comes the question...

Would this "XSVCD" be of better quality bearing in mind that they both have been encoded at the same resolution?
Also XVCD and XSVCD must have the same Bitrates according to the bitrate calculator.

So what's the point of MPEG2?

A few things:
1) XVCD is not widely compatible while MPEG-2 is.
2) bit rate is not limited to 1500bks for XVCD and SXVCD. There is no spec, it's a matter of your own DVD player whether it can handle it or not. Some can go as high as 6000 kbps.
3) MPEG-2 is widely compatible (for DVD) and support variable bit rate which is more efficient than VCD constant bit rate.

ktnwin said it nicely.

My DVD player will not play XVCD's at SVCD resolution and bitrates.

Thanks for the answers.

Mine will so far play XVCDs.

But I still need my question answered.

Will producing an XSVCD (ie with MPEG2 encoding) give me better results
than the XVCDs (MPEG1) I am creating?

According to this they both use VBR.
https://www.videohelp.com/xvcd.htm

Indeed the XVCDs I have produced have both had VBR and Higher than standard VCD resolution.

So what does selecting MPEG2 in TMPGEncs settings give me? As far as I can see it just unlocks 5 extra options at the bottom of the Video settings tab. Will choosing interlace give better results?

Thanks

MPEG1 (XVCD) and MPEG2 ((X)SVCD) will look fairly equal, given the same resolution and the same bitrate.

But will interlacing give better quality playback on my DVD player?
