No, those two game show feeds are not part of Pitchblue yet. They are still DVB-S QPSK MPEG-2. Read the following article
for more info on the Pitchblue status.
Personally I'd say that the improved H.264 codec provides a better source than the 35 Mbps MPEG-2 feed. That said, the Pitchblue mux is configured at 74 Mbps, 1 HD stream and three SD streams. The HD video that is feeding (an SD upconvert with pillarbars), is running about 14 Mbps. It is VBR. The SD streams are black with really low bitrate. The null packets are around 48 Mbps. So, the HD could get more, but currently isn't. The sitcom doesn't need the bits
I go along with coyoteaz's idea that it is a statmux issue. Someone needs to do TSReader graph outputs of the WABC OTA mux when the three shows are on and post the results. It is all conjecture until we see hard data.
