Need to resize slides for viewing on TV?

I have been working on copying a presentation to a VCD. The way I have
been trying is to use microsoft media encoder. Just in case others are
interesting in more details (since this seems to be a popular question)...

You can download for free the microsoft media encoder
(http://www.microsoft.com/windows/windowsmedia/9series/encoder/default.aspx).
This program will allow you to record your computer screen as a WMV
format (windows movie format). There are several settings, the ones I
have played with that seem to work best are for compression use file
download (computer playback) and for video use DVD quality video (2MBPS
CBR or the 1 MBPS CBR setting)- having the 2 pass encoding doesn't work
on my computer, not sure why. From there, press record on the encoder,
then play the powerpoint presentation. It will save it as a WMV file.
Then use TMPEng to conver this to a DVD or super VCD MPEG file. From
there use VCDEasy or whatever you want to make a VCD or DVD.

I am currently having two minor issues. First, when viewing the VCD on
the TV, the picture seems to jiggle just a little. It is not that bad,
but it is a little annoying. I think this may have something to do with
some settings in TMPENg. The other question is, I know that the screen
ratios are different on the computer and TV, so wouldn't it be better if
I resized my slides in powerpoint so that TMPEng just doesn't crop
things and make the slides video the right ratio? Anyone know what size
I should make the slides at?

I've read somewhere that you have to use the 800x600 screen resolution;
that's closest to the tv-resolution-ratio.

Success,

DVD has a resolution of 720x480 so 800x600 is about the closest you can set
on a windows PC.

Briefly...DVD resolution is either 720x480 (NTSC) or 720x576 (PAL).
In reality neither of these resolutions are exactly the 4:3 aspect ratio
that you get with on-screen show, but the resulting stretching/squashing
will hardly be noticable.
The cropping issue, however, comes from the fact that TVs overscan, i.e. you
don't see the whole picture.
Safest to allow a 5-10% margin around your slides.

The jiggling comes from the interlacing on sharp horizontal lines. Good
software gives you the opportunity to use anti-aliasing on presentations.
This solves the problem. If no available, change the source images by using
anti-aliasing/soften edges on objects.
