DISH Receivers, 129 and 61.5 sats

I'm a longtime reader of the forums, but decided to register to post about an issue I'm having.

I currently have a DISH 1000.2 system pointing at 110,119, and 129. I also have a DISH 300 pointing at 61.5. All those run down to a DPP44 in this order: 110, 119, 61.5, 129.

110 and 119 give great signals, but my beef is with 129. The highest signal I've ever seen on 129 is 30 and on transponder 6 it's even worse, peaking at 20 at the highest.

Now on 61.5, I'm pulling in a signal strength that hits 70 at times, just about perfect.

What I want to know is how the receiver decides which satellite to get the channel off of. For example, today I was watching the Big 10 network in HD, and the signal kept pixelating and crapping out every 5 minutes or so. The same thing happens with TBS which is also on transponder 6. I can watch a program for maybe 5 minutes before it dies and doesn't come back for 20 or 30 minutes.

What I want to know is WHY the receiver can't just switch over to the perfect signal it's grabbing from 61.5 for those channels. There has to be a way to get it to work. And yes, I know I could just drop 129, but my locals are unfortunately on it, so I need to keep it.

Any help or advice would be appreciated.

Aw, that's disappointing. I have the signal on 129 tuned as good as it's going to get, most people in the area that get 129 also get terrible reception.

Getting a better signal for HDs was just a perk of 61.5, I also am using it to get internationals, so I'm going to keep it pointed there.

I know my receiver sometimes decides to use 61.5 for HD channels instead of 129, I'm just not sure what causes it to do so. For example, it was pulling RAVE off of 61.5 instead of 129, but had no reason for why. The only channels that really suck on 129 are just the ones on transponder 6, and those are the only ones I really want it to grab off 61.5 instead, but I guess I can live without Big 10 and TBS.

Well in my case, since I have the DPP44, I just remove it from the switch. If you still just have the receivers connected directly to the built in switch in the 1000.2....I'm not really sure, honestly.
