How to convert MPG/MPEG to iTunes for Mac OS X

"I imported .mpg videos into iTunes. I am having two issues. First off is the tagging of these files. After editing the tags to change them to TV show and add episode number etc. it appears that this information does not save. After I sent these files to a different computer all of the tag edits were gone. I also cannot add artwork to these videos. Do the tags get changed in the .mpg or in iTunes?
