<p class=MsoNormal>If that's the case, then we can't help you. Only the
manufacturer of the STB can do help you with problems with their product
(unless they want to contact me directly about this, in which case I'd be happy
to work with them).<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>However, as I suggested in my previous message, I suggest
that you first use the "testMPEG2TransportStreamTrickPlay" utility to
generate Transport Stream files that represent the effect of the server
performing a fast-forward or reverse-play operation. You can then try
playing these files using a media player (like VLC), or stream them to the STB
(without any 'trick play'), to see if they're OK.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>Note, however, that the Transport Stream indexing (and thus
'trick play') operation might not work on an encrypted Transport Stream file
(depending on how what parts of the MPEG data are encrypted). But again,
that's something that you can test using
"testMPEG2TransportStreamTrickPlay".<o:p></o:p></p>
