[MEncoder-users] Convert MTS to MP4: Video and audio out of sync

[Ooe Eoo]

Thanks for the info, Bill. I guess mencoder was the best option for video rendering in the past before ffmepg has become popular.
It is a digital asset management software. I will not mention the name here.

I was told about that time on this mailing list that MEncoder had not been 
maintained for about 6 years.  Could be 10 now.

I am interested to know what application are you using that has MEncoder?

Sorry for posting garbage on the last post.  I accidentally pasted 3 times 
by mistake.  Also, They do not like top posting here.
