Dish 148, channel 581, 582 gone! Help

[yaoeryaoer]

Channel 581 is always black today and when I switch from other channels to 582, the error 002 appears on screen. Says lost of signal. Besides that, other channels on dish 148 works perfectly and signal seems good too. I wonder if it is just me, or dish is eliminating 581 and 582 from 148W, since 121 W now carries all the Chinese channels now. I am using an atmega with 2800 receiver. My 119 W works perfectly now. Just 581, 582 two channels.
Thanks for any helps

not sure of those particular channels but some of the internationals are starting to go Map 57, which means they'll be lost on atmega
