Any software like YAMB for splitting h.264 MP4 ?

[JonRead]

I need to split 4gb+ h.264 MP4 files to play on a PS3 via USB stick. YAMB is very good but causes crashes often and sometimes jerky playback. Is there anything else like YAMB out there that I could use ? I don't mind freeware or paid. I just want to split without re-encoding, thanks.

You might give MP4Muxer a try.

I am pretty sure it splits. If not, have you tried the newest Yamb? 2.1.0.0 beta?
