This is my first post on MacRumors. I am a big fan of the site and have been reading for years but have never posted. Anyways, I will get to the point. I just got a high end Mac Mini with the dual layer DVD burner on Sunday and I had some old DVD's that I recorded using a Panasonic DVD Recorder that I wanted to combine on one DVD. They are all sports videos so there is a lot of fast motion and such. I wanted to burn them on my Mac Mini because I wanted to add chapters and do a little editing. So I got the multiple DVD's and and used Mac The Ripper to grab the .VOB's off each one. Then I dropped it into Drop2DV and then edited the resulting .dv files in iMovie. My final movie was about 2 hours and 30 minutes. So I put it into iDVD, made a nice new motion menu with Scene Selections and everything. When I burned to a dual layer DVD+R DL using "Best Quality" because it is so long and played it on my Mini, it played great. However, when I take it to one of my other two DVD players (the Panasonic and the other is a Samsung), the parts that have fast motion (which is most of it since it is all sports stuff) are very very choppy and it is really annoying. Does anyone know why this happens? Is there a setting in anything that I can change to fix this? This was one of my main reasons for getting the mini. I wanted to consolidate a number of my DVD's. Any help would be appreciated. Let me know if there is any other information that you need. And no, it was not a fluke thing because I tried to burn another video to a DVD-R and the fast parts in that video where choppy as well. I have no idea what I am doing wrong.
