Have you tried Nero? Very handy program for SVCD's. Dunno if it
matters, bit this might be throwing you off.

Also, you might want to burn a non-complient SVCD WRT the audio -
upconverting from 32KHz to 44.1Khz can add funky harmonics to the
audio, some of which can give those of us with good ears headaches.
Most players will play a non-audio-standard SVCD - My apex will,
anyway...

The funky dots you're seeing is the Closed Captioning data. It
(normally) hides in the overscan regions of the TV netherworld...
check out my page at:

to see the clipping rates to get rid of this if it bothers you.

I have a few hints - I'm at work & video setup is at home, so I can't
walk you thru *exactly* where the settings are, but there's two
different "ratio" settings you need to check on.

The first is for what you want to output, and make sure it's 480x480
4:3 NTSC (not VGA) and also, if you click on "input source" (the next
tab over) make sure that the input is *also* 4:3 NTSC and not 1:1 VGA
- this can make your video wonky.

Warning: *sometimes* TMPGenc will set/reset this setting at will, so
it's good to double-check it on occasion (sp?), especially before
that nice 8-hour transcoding session. ;-)

Anyway, I hope this helps and if you have any other questions, please
feel free to ask!

Laterz,
