Recently, I converted home movie taken on Sony TRV 240 digital 8mm camcorder through a firewire using the pass through software to dvd+rw. I used the ARC showbiz dvd software provided by HP DVD +rw burner to do the conversion. However, when I viewed the dvd +rw on Power dvd, the video and audio was very jumpy. Could anybody tell me what is the problem and how to correct this problem?
