Hi Everyone

Need advice please

We have a Sony Handycam Camcorder DCR-TRV19E. I downloaded the film from the camcorder through Pinnacle and then added my templates through Nero where I then burn onto a dvd-r disc, but when you view on another computer its grainy, is this the software that I can using or the camcorder, also is this the right camcorder to use or is there a better one?

Thank you
