Hey Shane,
Thanks for your answer. So far I have use 29.97 but sometimes I find that when i had motions to images is not always very smooth especially when there is long distance to move, for vertical pictures for instance.So I thought that could come from the frame rate! Also as much as I can , I convert to format that i can show from computer rather then from a dvd. I found that DVD lower a lot the sharpness and the quality in general of the images.
Cheers
