As I stated above, I have try using different frame rate but all fail!
"I have try using different frame rate for encoding, the most matching/sync one is 25fps, thought it is sync with video and audio, but the video is going not smooth. According from the log inside the ripper, the DVD is in 29.97fps
Input #0, ifo, from 'H:\VIDEO_TS\VTS_07_0.IFO':
Duration: 01:53:56.4, bitrate: 384 kb/s
Stream #0.0: Video: ifo_v, yuv420p, 720x480, 29.97 fps(r)
Stream #0.1: Audio: ifo_a, 48000 Hz, stereo, 384 kb/s
if I set the framerate to 29.97, the audio and video are both smooth but not sync"
how can I solve it?
