I also would like to see the CW added to PTAT, but I think Dish would run into a marketing problem if they tried to advertise it nationally. Dish does not carry the CW in every market. Some markets get a CONUS feed of the CW in standard-def, which is obviously not on the same transponder as their HD locals, so the feature would not even technically work in those markets. I still would like to see Dish add CW to PTAT where they can, assuming that the hardware can technically handle it. I agree with the comments about PBS being too hard to include in PTAT, since many markets have multiple affiliates. Other markets only get a national feed of PBS, so the feature would not work for those markets. Again, even if adding PBS to PTAT was technically possible, Dish would run into a marketing problem with different markets being able to record a different number of channels. I think that is the main reason Dish limits PTAT to just the big four networks.
