Hello, I am a newbie to DVD burning and I just bought a LC GSA-4163B DVD writer and I was trying to burn a backup of a movie I own when I noticed some problems. So I tried to experiment with different settings, and came up with the following results. First, I started burning a movie using PC Shrink + Nero Express with 75% compression (4x) onto a cheap brand DVD-R and I did not select deep analysis nor any enhancement. After finishing burning the disc, I tried to play it on my home DVD player, and the movie and sound stuttered on some scenes. Next, I tried burning the same movie using the same configuration, EXCEPT I changed the media to a SONY DVD-RW. After burning, the movie worked perfectly on my home DVD player. Third try, I tried burning the same movie again using the same configuration, this time with a SONY DVD-R disc (8x), and stutterng problem occured again. This time, it seemed to be worse than the first disc I burned with cheap no-brand DVD. Last try, I tried burning the same movie with the same compression, and this time, I check both "deep analysis" and "enhance sharpness" (which took more than an hour for the whole process). I used the cheap no-brand media again. After burning, it worked perfectly on my home DVD player. I then noticed that these stuttering discs (#1 and #3 experiment) ran perfectly smooth on my PC, and also on my PS2. But why does it stutter on my home DVD player? How come my #2 and #4 try did not stutter? I really don't want to go through the deep analysis and enhancement process for every disc I try to burn because it takes too long. Will someone please englighten me? Thank you very much.
