Can't take credit for this just a copy and paste from another thread
(couldnt find a link to it on google)
TS, ("http://www.linuxtv.org/wiki/index.php/MPEG2_Transport_Stream"), is
the original/raw format used in the DVB data stream. When Myth records
in TS mode it filters out unwanted pids (other channels & unwanted
streams) and does some minor rewriting of the PAT/PMT etc, but basically
it saves the data in its original format.
In PS mode, Myth converts the incoming TS data into PS
before writing it to disk. PS format has slightly less overhead than TS
so it takes a few percent less space on disk, but it doesn't cope with
errors as well as TS, and since the TS->PS transform in Myth is pretty
"quick & dirty" it's likely to contain bugs and it won't handle the
"advanced" features planned for Myth (teletext, subtitles, MPEG-4
