I am evaluating Clone DVD Mobile for ripping my dvd's to play on WMCE (Windows Media Center Edition) for my home theatre. I ripped The Matrix, TinkerBell, Madagascar and Curious George as tests. The video quality was set to the highest available because of the large screen size I am using for playback. All other settings were standard for the Zune MP4 output file. (I don't know what a Zune is but it was the only MP4 profile I saw in the list). The audio is delayed by about 0.5 seconds on all files when played back in MCE which is unacceptable for a home theatre. To get it to playback in MCE I had to download the K Lite codecs (MCE doesn't recognise MP4s without additional codecs). I have ripped other DVDs to MPEG 2 format and they work fine (using a different product) but the file size is outrageous (about 4 to 6 Gig each). Is there a simple fix for the audio delay? I absolutely do not want to compromise on the video quality and will soon start ripping bluerays as well. I would like some advice as quickly as possible so I can complete the evaluation and make the purchase of the appropriate software. Thanks Slysoft... your software came highly recommended by a geek friend of mine - I would like to make my decision soon so I can rip the rest of my catalogue over the holidays. Thanks again.
