Uh oh.

I bought XMuxer Pro with the idea of creating TS stream with H.264 for the CES show in January. Now I've discovered that I can't set the transport rate. In fact, I can't even *determine* the transport rate of the transport streams this software generates!
Please tell me, how shall I know what rate to set on my packet injector/modulator to inject these streams into set-top boxes.
And are the streams CBR?
