Anna, you need to give detailed list of your settings, all your settings. All the steps you are taking. Comments like, “I checked the settings and they are correct” are not helpful. What do you mean by stalls? for a sec? stops the DVD? Freezes on that frame?
You are simply all over the place is describing what you are doing.
+R media is never recommended. This is more of a playback thing, -R are safer for compatibility.
Within DVDSP there are 2 ways to make a disc. Burn (I never recommend) or Build and Format. Once you build a project you can just use Format if no changes are made to the project. You should be using the Build and Format. Yes it is a good idea to uncheck loseless linking.
The m2v files need to be clean and single files within each track. The audio needs to be ac3 and not uncompressed PCM.
So if you want more help you need to provide a simple step by step list of what you are doing and details of your settings.
Also what HD are you using for your build Video TS, how is that formatted.
