Try "cat ts_stream | ts2av_pes |av_pes2ps "
That should be faster and avoid the C++ buffer problems. The ts2av_pes
only takes the first audio and video pids from the PAT and PMT, so you
may have to change that. You have to be aware that the resulting PS may
not be well muxed depending on the incoming TS. The headers also do
not reflect the true buffer sizes.

The windows player should play it. The programs mentioned above use
the same routines as the driver for those transformations.
