Can't convert MKV -> MP4

[LuckyMan]

Hello! Since Version 11 (MAC) I can't convert MKV to MP4 (H.254). Each file is converted to the end, but can not be opened with VLC or another player. With V10 there is no problem! Thanks for helping!

Can the same mkv file be converted using older (v10) version of DVDFab to do the conversion?

Please provide the dvdfab_internal.log file and send us one short problematic mkv source, so that we can test it and check it out as soon as possible.
Please check PM for FTP info. Thanks.
