I had burn tons of DVD video for my father. Everything goes smooth until one day, when I played the DVD, the video stucked, but the audio was still running. I then tried to burn it again to a new DVD, I found out the encoding process goes very fast, it usually takes a long time to encode the file. I usually burn a video file with 8-9gb size to 4.7gb DVDR, and the video can be fit after encoding, but this time i choose a video with 11gb and try to fit in the DVD. Is it where the problem locate? Please help.
