have experienced simular problem and the forum could not help as the technical support
here is the solution that worked for me:
in the produce mode chose any desired output eg. mpeg4, mpeg2,h264 but it cannot be defoult format, panasonic cam sometimes do not record in progressive modebut the frames are registerd as a main field first , so you have to have to tick the custom mode and try several options, clic on the pen icon below and a bozx will open with several options for your video and audio, go for progressive and main profile, burn it, try to watch it, if not ok try other options that will work for you, the solution to your problem is there
