Hi,
I'm trying to back up all my DVDs. Most are just fine, others have problems when I try to play them on my TV. The audio is good, but the video seems to pause and then jump to where it should be every 2-3 seconds. It is super annoying. Any suggestions.
I am using "Mac the ripper" to extract and "popcorn" to compress and burn. I am not very experienced with either program, so I may just have settings wrong?
Thank you VERY much

Brandon, welcome to macosx.com
Choppy videos can be due to many factors: home dvd player too slow to decode videos, "not so good" media
As a test, for one movie you find choppy on your home dvd player, could try to perform (1) a full disc extraction in MTR and (2) suppress every bonus, subtitles, foreign languages (if any) in Popcorn - so supress them in PopCorn but not in MTR -, so to only keep the main film.
That's my method: full extraction MTR than "tune" the stuffs to be burned into Popcorn.
Is this better ?
Regards
Philippe

Thanks Philippe,
I tried the DVD that wouldn't work right in my DVD player on a friends DVD player--and it worked fine. So, obviously my DVD player must be slower/older/crappier than my friends.
Would burning only the main feature solve the problem for my slow dvd player?
Thank you very much (again)

Yes, sometimes, because in this case Popcorn has to choose a lower compression rate..and sometimes, does not compress at all.
I face this with for instance, MatrixReloaded: keeping the file + english/french soundtracks + english/french subtitles leads to a 26-30% of compression in PopCorn.
On my home DVD player, speedy scenes were choppy.
I made a new DVD while keeping on the film with the french soundtrack; Popcorn compression drops to 5%; and the film is not longer choppy in speedy scenes.
My rule is: if PopCorn compress for less than 10%, and if the film is still choppy, yes, the player is a crap one.
What you can also do is cleaning the lens of the player with a CD lens cleaner, you know the one we use for cleaning the lens of the car cd player. Perhaps this will help.
