What's the best tool to convert MKWs to MP4s (to be played on ATV2)? I've used Handbrake for years and it works well but it seems long to encode. I tried MP4 Tools and that was quicker but not sure if I am choosing the correct settings. From MP4 Tools: Should I be choosing "Pass-Thru" under the audio section even though it is solid Red? "If Red, the option is not recommended". If I choose AC3 5.1 I don't get an audio. I've been selecting Pass- Thru and it seems to work okay but just wondering if I am losing any sound quality.... Thanks for any help!
