Pinnacle studio 14 problem with DVD export

[Alternator]

Hello to all. I have a problem that can't get solved. I Have Canon HF S11 NTSC HD camera, I get videos in .mts files. Files are 60i - 24 mbs in HD. I open them and edit in pinnacle, all OK, But when DVD is done video do not run smoothly, is have small breaks, in play ( do not know how to name it, stuttering or what? ) Sound is OK. I tried differend project options, but no luck. Any suggestion? Any other DVD authoring program to suggest? What is best projec settings for DVD?

TNX ALL!!!

There is no answer so I tried old school solution: Reinstall. But it's not easy task, I google it and finde some solutions http://www.ehow.com/how_5089232_remove-pinnacle-studio.html and http://declic-video-fx.com/language/en-US/Download.aspx#443 for RegDelete, So I unninstall all Pinacle stuff, run RegDelete, than instal fresh Studio 12 (for start) and DVD result was smooth video, finaly. Hope that heleped similar problems.
