A client of ours has asked us to integrate Gallery 2.x on his web site. He also would like the ability to upload MPG videos that appear as part of the galleries as well. Is this possible?
you can upload any file to g2.
for video files, g2 can create thumbnails (an image snapshot) and it can show them in an embedded video player in your browser.

Note that for it to auto-generate the thumbnail your server will need to be running ffmpeg. Most shared-hosting packages do not run ffmpeg by default. However, you can add custom thumbnails for each movie if you wish.
Also, if your client just wants people to be able to view the movie on-line (as opposed to download it for later use too), then I highly recommend converting to flash .flv for use on-line. Flash is a smaller file size and better supported than even .mpg.
Thanks for the help, guys!
