First, 521 shows up twice. One for HD, one for not HD. My kids wanted to watch Open Season on channel 521 HD. I tuned to it. It asked me to pay $4.99 for the showing. Um, I subscribe to this channel, why would I suddenly have to pay an outrageous $5 to see it? Then i went to channel 520. on the HD channel it's "Spiderman 3" on the non HD, i get a sunday ticket notice. What kind of random goofiness is this? This is with an HR21-700.
