They are the software that performs the conversion.
"Codec" is a contraction for "coder decoder".

Get GSpot and study what it tells you.
Frame size has to do with how many pixels make up a frame. For example
D1 is 720x480 width x depth. Bit rate has to do with how much
information is stored for each frame.

How do you play it now? And how do you intend to play it after
conversion? If it's on the computer, there are any number of places
you can get the proper codecs. But if it is on a DVD standalone you
must have the MPEG4 codec installed. You might want to check with
LiteOn to see if they have a firmware revision that supports MPEG4
format.

MPEG4 is already very compressed so you will have to sacrifice
resolution to get it any smaller. Another format is not going to
result in much size reduction from the already super compressed MPEG-4
format.

Total Video Converter has about 6 different MPEG4 formats so you will
have to pick one that is suitable for your use.
ConvertXtoDVD is going to result in a lot larger file size because it
converts MPEG-4 to MPEG-2 which is an older compression standard.
You might look at DivX/XviD (the latter is preferred) in an AVI
container but your player must have the proper codecs installed.
