Can't shrink/re-encode video to original specs

Ok, I'm not sure if the title is even correct in technical terms but I'm hoping you guys understand.

I'm using a program called ArcSoft TotalMedia Extreme 2 to convert videos I captured from a Hauppauge HD PVR. The original files I captured is about 1.6GB - 2GB+ for a TV show I wanna be able to watch later on.

I used the MediaInfo application to get the specifics on the coding of the video which I shrink down to about 360MB or so. This is the info that was pulled from my older file which I converted some time back:

ID : 1

This below is the new file and has a different resolution and the application won't let me make 720x404. Only 720x480

I see a bunch of different info and I want to make my newly converted videos like the one above. I'm assuming it's the codec that's installed which seems to be the default ArcSoft version. Not sure which version and where to get the original codec I used to get the file to be the same as before.
