Front Row plays RipIt videos just fine, but there's a missing step.
Here's what I do:
1. I locate the ripped file.
2. Right-click (control-click) on that file, and select "Show
Package Contents" from the drop down menu. This displays the file's
contents (this works because that file is actually a special kind of
folder).
3. I take the enclosed VIDEO_TS folder and drag it out somewhere
else. I delete the now-empty original ripped file (the special kind of
folder).
4. I make a new folder and name it with the movie name.
5. I drop the VIDEO_TS folder in that movie-named folder.
The next step is not strictly necessary to play the movie in Front
Row, but it will provide an image for Front Row to display, so it's
very helpful.
6. I Google the movie on the net for an image of the dvd or a
poster of the movie. Note: Make sure that the image that you find is a
jpeg, or you can convert it to a jpeg yourself. Most are jpegs, so
you'll probably be fine.
7. I save the image to my machine and rename it exactly
"preview.jpg" (no quotes). It's important that it's exactly named that
way -- preview.jpeg, for instance, will not work.
8. I drag the preview.jpg into the movie folder containing your
VIDEO_TS folder.
The movie will now play in Front Row.
It looks like a lot of steps, but it's really not bad. If there are
other ways to make the file playable, I'd don't know them. I also have
no idea why the RipIt folks don't have an option in their software to
output to a normal folder. They're the ones who make this nonsense
necessary. I'm sure there are valid reasons for it, but there are also
enough valid reasons against it to argue for a preference setting.
They've done so many things right with this software, it's a real head-
scratcher as to why they've neglected this. I'm betting it's a simple
as someone there never uses Front Row and lacks the imagination
required to add this feature for those who do. If you're listening,
Little App Factory (they're probably not -- I'm pretty sure they moved
the forum to Google Groups so they wouldn't have to deal with
customers asking when they'd have a fix for movies that wouldn't rip),
please, please add this preference.
