Having problems converting from MKV to Mp4

[brucexx]

I am having a strange issue. I have quite a few movies in .mkv (encoded in h264). I tried using xvid4psp to change the format to .mp4 to be able to play it on my PS3 with a COPY set as video encoding. The process get almost to the end and then I get always mp4box windows error and nothing happens , xvid4psp creates a file but it is not usable.

I figure I just grab the video stream from the file and try something else but when I use MKVExtract I can see the content but when tiring to extract I am getting: Error: Unrecognized command line option ''. and unusable h264 file. I also tried to get the file from temporary directory from xvid4psp but it is also unusable.

Did I mention that the file plays just fine when in .mkv format

I am puzzled anybody has any idea of how to proceed in this situation

Tanks in advance.

You can always try Ripbot264

I am just trying it. Is there an option to copy the video stream instead of encoding ?

Thanks
