Okay, I first used HDVsplit to read a HDV tape I made using CS3. It seemed to have some dropped frames at a number of places, so I decided to make a new tape. I had the m2t master files on my hard drive, so I decided to try the cs4 program. I used cs4 to export these files to my sony tape unit. No visible issues. But, when I used HDVsplit to try and read the tape, using scene detect, it looks like it thinks there is a scene detect break like every second. Never saw this issues with CS3. Any ideas?
