4. Fix the guide so you can browse channels and then tune the one you want to go to. It seems that if I 'pre-view' too many channels it won't let me pick the channel until I exit out of the guide screen and go back in.... or change the channel outside of the guide.

5. Skew / polarotor control (like many of the Pansats have)

If a new model:

6. Component and or DVI output

7. HD & 4:2:2 capable

8. (I know this is a stretch!) - ATSC tuner as a module / option.
