Joining Mpeg files

[asriel]

Hi,

I have 4 mpeg files of about 800mb each. I was wondering can these be joined to make 1 large mpeg. I tried Combimovie, it joined them ok but when you played it back only the first mpeg was there.

File size of mpeg was 3.2Gb, but it stopped where the first mpeg would have stopped.

Any help or advice on what to do or what programs to use would be much appreciated.

Thanks
