Sound out of Sync in conversion

[opala]

Well I read few threads here about that but it didn't help.
I've tried to convert some MKV files X264 with ConvertXtodvd and the sound always out of sync, how can i fix this?

i have 3.5.1 Version.

You upgrade to latest convertxtodvd 3.5.3.

Or try DVD Flick or FAVC or TheFilmMachine.

thanks, i'll try it.
another question is instead of using these programs, is there a way to convert the MKV 264x to avi with subs, i've already tried with All2Avi but it changes the aspect ratio.
my objective is to put avi videos as much as possible to a DVD disc (4.7) or using these programs like Converxtodvd to add one movie and preserve good quality with subs.
I find the MKV files very attractive because of their good quality and low size(relatively).

any suggestions?
