I have now changed my application to create exactly what ts2ps creates.
Now I notice that neither mplayer nor vlc play the stream created by
ts2ps.

Vlc gives tons of error messages like this:

  [00000365] main video output warning: vout warning: early picture skipped (47722279483)
  [00000359] main audio output warning: received buffer in the future (47722179597)

no audio and black video :-(

If I remove the PS pack header and the PS system header (stream-id 0xba
and 0xbb) then both play the stream, but no STB plays it :-(

Next, I tried:

With this command, I get hopping video with VLC.

It seems to be a mess.  None of the programs seem to produce proper
streams.  Only mencoder seems to generate a proper stream.  But AFAICS,
mencoder completely decodes the stream and re-encodes it again, eating
up all the CPU.

Any more ideas how to do the conversion?

BTW: Can anybody recommend a good book on the topic?
