So I have this 10GB file HD movie. I tried to play it with KMP player, thought free is good, nope, this kmp player cannot play my HD 10gb file, the audio did not sync with the movie video. Then I tried the famous free VLC player, nope, don’t work well either, the audio sync but the picture distorted and sometime frame skipped, very annoying. Then I come back to my famous PowerDVD Player, I even have the old version and it’s working fine. Although I tried version 12, it kept on closing or shutting down by itself, so I tried the PowerDVD 13, it work perfectly. Audio sync with picture, and picture video is perfect, no distortion of any kind, very smooth. Bottom line? Cyberlink PowerDVD baby! The version 13 especially can play many different formats not just DVD HD disc but also the files form such as MK 20GB size, it can read smoothly! thumbs up! Cyberlink!
