Transfer Video to DVD?

This morning's email brings a request from De Prez Allen Laudenslager.  He's received a note asking about transfer of a video to DVD.  Can you help?

"My name is Aarti, and I am new to both Prescott and Macs. I have a MacBook Pro and am looking for some help.  I volunteer with the Veterans History Project, which conducts interviews with local veterans for the national that is organized and archived by the U.S. Library of Congress.

"Our video equipment is the Sony Handycam 105. It was donated by Wal-Mart. Unfortunately, the Handycam only uses mini-DVDs, which can't be placed into a Mac. Furthermore, the camera does not have a port through which to be connected to the computer.

"I am at a loss for how to transfer the video to DVDs that I can submit and give to the Veterans. I borrowed a PC to copy the files from mini-DVD to my external hard drive. But, these files are .vob, .ifo, .bup. None can be opened by my Apple software. I tried advice I found on Internet searches, and downloaded a couple of different "ripping" softwares to convert those files to .avi or.mpeg. Still no success.

"Would any of you have advice? Thank you!"
