Yeah, you need an NTSC monitor or straight TV (I suggest a small LCD TV for the budget minded) to see what your output will look like. Your computer shows video in progressive scan (that whole ‘P’ thing) and your standard scan TV (HD included) shows video in interlaced (‘I’) frames. As Rob said, your computer will not play back interlaced video without those ‘jagged lines’ as it is trying to show them in the progressive format.
You only need to use deinterlacing if your final product is going to the web since all computers show their videos in ‘p’ mode. Even then depending on your NLE, the result won’t be perfect and may cause other issues. The most likely reason you’re still seeing jagged lines on your DVD’s is probably the player and or the set you’re watching it on may also progressive scan.
I would have to disagree with Rob about shooting in progressive mode as it does remove the interlacing that occurs during subject movement as the frames are recorded progressively not as overlapped scanned fields. On the otherhand, progressive scan has its own issues with ‘motion artifacts’ which occur during fast subject movement. The least expensive option is to shoot it was well as you can, use a compatible format monitor and bear in mind your final output format so you can make any necessary adjustments.
