H.222 Transport Streams (there is no such thing as an "H.264
Transport Stream") are fairly simple animals, and there is no
"file format" defined for them as such.  They *are* the container
format, so the only sensible file format is to store them without
any further fiddling about.

To find out exactly what is in a TS saved by your STB, you could
try using "tstools" (http://code.google.com/p/tstools/) to take
it apart and see.
