I was typing as SuperLeo posted but here is what I have found out

It's really a shame because the PS3 allows me to copy all these moves and blend them together into one movie.
As Blu_One said the m2ts does contain audio and video. I have been able to replicate your problem and I believe it might be because the PS3 will not read the HD audio from the m2ts file. I have tried file 21 as you mentioned which is Dolby True HD and file 24 which is DTS HD. Neither work.
I tried downconverting with tsmuxer as mentioned in post 2 here
http://www.networkedmediatank.com/showthread.php?tid=16808 and it worked for the Dolby HD to AC3 but not the DTS HD to Dts
I would suggest using the info found in post 2 here

I have done this successfully while learning about these discs and testing for the PS3. You can drag the individual m2ts files into multiAVCHD to create your own greatest hits so to speak but you will lose the great menus that have been created by the guys who put together these discs. Unfortunately since the PS3 can only have one AVCHD folder on the root of the external drive ( it can't see multiple partitions either, i tried) you need to have a separate drive for each demo disc that is found here at AVS, or put together your own as i mentioned above.
Ultimately that is what I will have to do.
Full credit goes to the disc creaters as I am just dragging and dropping files and these guys did all the work. Unfortunately I have to work with what I have which is one external drive and a PS3, which leaves me limited in my ability to enjoy all the discs
