I have problem. After formatting my hard drive and installing everything again I don't have any MPEG Layer-3 formats
Did you ever manage to find a solution? I have the same issue with no options in MPEG Layer-3
I also have an issue where the GUI will not create the .dat when adding the command line. Going ahead without it leads to a video that isn't synced with the audio and appears to be running in slow motion.
It wasn't a re-format that resulted in the issue in my case.
There doesn't seem to be much info elsewhere on this topic.
Anyone here who might know something, seems to be avoiding these particular questions.
