1. SA HD and DVR's allow for Native HD Resolution Pass through. 1080i channels can come over in 1080i. 720p channels can come over in 720p -- all without powering the box off and going into a menu screen every time you want to change the resolution. The Moto only lets you pick ONE HD resolution.. not both. IE) Convert all 720p channels to 1080i, or convert all 1080i channels to 720p. This triple conversion does loose quality... I've checked and 720p looks better on ESPN,Fox,ABC,etc.. while 1080i looks much crisper on CBS,Discovery,NBC,etc.. So on my TV my box is doing this:

Looks Soft and lost detail (Triple Conversion):
720p channel > Converted to 1080i > Converted to 768p at PDP

Looks really sharp and clear:
1080i channel > Passed through > Converted to 768p at PDP

or when set to 720P...
Looks Really sharp and clear:
720p channel > Passed through > Converted to 768p at PDP

Even DirecTV, Dish Network, and PACE set top boxes have multiple resolution selections available, allowing you to send the proper broadcasted format to your HDTV, without being touched. I, along with others have been posting this issue with Motorola boxes for well over a year now. I'm surprise no higher ups at various MSO's or even Motorola themselves haven't found these posts on these types of sites, or even through Google searches. The best thing a company can do (Comcast or even Motorola) is to scour the internet and get REAL WORLD user opinions, wishes and complaints. It only can better their products.
