Is there a free software that can join two .m2t files together?(opposite of HDVSplit)

I have two *.m2t files that I want to join together, without any encoding/rendering. I'd like to have one single m2t file. (the opposite of HDVSplit, which splits one m2t file into several smaller ones)

Thanks for your help!

if u work in ms windows, then open MS DOS window and from command line enter:
C> copy/b m2t_file_name1 m2t_file_name2 resultant_m2t_file_name

that's it.

Thanks! I tried this method. Combined several M2Ts
from command line... Works perfectly when the resulting
M2T is played in Playstation 3! :)

Sorry for my lack of MS DOS, but I need to join 2 m2t files, and haven't tried this yet. Before I do, I have several questions;
1. Do these 2 m2t files need to reside in the root of C drive before joining them?
2. Suppose my first m2t file is 001.m2t and my second is 002.m2t, and I want the result to be 003.m2t.

Using the above scenario, what EXACTLY do I put on the command line?

I thought there is a + sign in the syntax. for example.

COPY /B 1.m2t + 2.m2t NEW.m2t

To make it easier, you can copy both m2t files to C:\ root. Then hit Windows-R and type
"CMD" then enter. It opens a Command Prompt windows. type "cd\" to switch to the room directory. Then enter the copy command.

Ok, I finally tried it and this worked in joining my files:
C:\>copy/b test001.m2t+test002.m2t result.m2t

Or you can just do this

copy/b test001.m2t+test002.m2t

Then the test001.m2t will be overwritten with the joined content.

You know what? This is not working for me! I assumed my files were joined together, because the file size was double of what it was before. However, when I played it back, only the first file was seen. How strange. I tried it on 2 computers, same thing. I also tried:
C:\>copy/b test001.m2t+test002.m2t
which should have resulted in 001 being a new joined with 002. When I play it back, the file size is double of what the original was, but the length of the clip was the original 001 file. What am I doing wrong?

I also tried this file joiner, but the result was the same.... resulting file size looks correct because it's the sum of both files put together, but the length of the result is only 1 clip.

That is because the files were joined but the metadata inside the files wasn't updated.

You can not join m2t files that way.

Re: Is there a free software that can join two .m2t files together?(opposite of HDVSp

You can join your files together if you rewrap them into a mpg wrapper then use the "copy" trick on the mpg files.

This does not re-encode them or reduce their quality. It only changes their container.

Once you have the file put together you can change the container back to m2t.

A program called ffmpeg will change containers for you and its free.
