Is there ANY software I can use to make a DVD playable by PC's Macs and DVD

Question

OK, I have been fooling around for over a year on this and still have no answers. Here's part of my original post. I have home movies that were done with film and transfered to m2p files. I want to make copies for my daughters, who have DVD players and PCs. One has a Mac. I used Toast 10 to convert to mpeg4. I burned a DVD with Toast. It plays on the PCs and on the DVD players, but NOT my Mac. I tried H264 format...same thing. I can burn the mpeg4 files to a DVD with Quicktime Pro and they play on my Mac, but not on the DVD players. Commercial movies play on anything. Is there anyway I can do this on my Mac???

Thanks Jeremy, here's what I can tell you. I played a commercial DVD in my Mac and it played fine. It opens up with DVD player. I put the DVD I made in the Mac. I made several of them in different manners. On one, I converted the m2p file to mpeg 4. Then I burned in Toast , selecting DVD_video. On another, I did a convert to H264 and burned it using DVD_video. The third I just copied the m2p file into Toast and used DVD_video. When I did the burn on all 3, I went to the menu option and put in a title and used the passport style for my title page.
When I put the DVD in the Mac, it automatically opened to the Title page, in passport style. When y ou click on the play button, nothing happens. Can't fast forward, can't open menu, etc. I closed out DVD player and went to Quicktime player. I clicked on "open file" and selected the DVD in the finder window. When I click on it, it opens to the Audio_ts and Video_TS folder. Clicking on the video folder I get 8 different folders in there. Clicking on most of them does nothing. Clicking on the one that looks like a Quicktime folder, I get the message " not a movie folder" I also tried to open it using VLC player. It opens u p the Title page, like DVD player and you can't get it to play.
So now what do you think!
