Non Continuous Video using ConvertXtoDVD

Please forgive me, I’m new.
I am trying to make a DVD from home made movies. I have a Canon HF200 and the files I saved on my PC are .mts type. I used the max resolution to shoot the videos. I’m using ConvertXtoDVD software to convert .mts file to DVD format and to burn them on a DVD. The conversion process takes a while, which is fine. After the DVD is burnt, I play it on any DVD player, the sound is OK, but the video is not continuous. It seems as though it is missing frames. I used the software with all default values. Is there something I need to do with the software settings?

Please please please help me.

Thank you in advance.
