I too have the 722 small picture issue/feature!
I told my family not to even watch the HD channels on TV2, and not use the aspect button. I hope this corrects the problem. I sent a link to this thread to DISH, and this is what I received in return. Talk about customer service and when it comes to DISH support, one hand doesn't know what the other hand is doing...
Thank you for your email. We apologize for any inconvenience this issue has caused. Unfortunately I am unable to assist you via email any longer as a technician is required on site to resolve this issue. I will email the local office requesting a field service manager come to your home however you will need to call us at 1-800-333-3474 to set up the appointment.
Funny, I send them a link to this thread where others are having the same problem, and they tell me they can't help me and that a technician needs to come to my house. I have had two come in the last two weeks. Then posted above, DISH states that they are aware of this problem and that it is a software issue. I truly don't think they have a clue. If anyone finds any more about this problem, please let me know. And if you could, please send me links to other threads that discuss this issue.
Thanks so much!
Mike
