Is it possible that your lossless transcode is modifying something else,
audio, etc.  Is the resulting file the same size?  Is it fragmenting during
recording, while the transcoded file is not.  Are the recording and the
transcoded file on the same disk/array, same mount point, same permissions,
etc.  The only way to be sure that your playback issue is not the network is
to eliminate the network... same story with all of those other variables,
take them out of the euqation.  Copy the file to the windows machine and try
and play it.

You miss the point... I am trying to remove the backend from the equation as
a troubleshooting technique.  Of course you want to use myth with those
tuners, this is the mythtv mailinglist afterall.  If you can tune and watch
the live stream, then you know your machine is up to par for playback and
that your HDHR isn't corrupting the stream in any way.

I doubt that is the issue then, still could be a configuration issue on the
laptop, but MPEG-TS is not so much different than MPEG-PS that I would think
you could inadvertantly configure your computer such that it would play one
but not the other.
