DishPVR 721 slow channel changing

[chaseme5]

Hello everyone,
I recently bought a 721 from ebay. After spending $200 on upgrading to dish pro plus and new cable because my old cable could not handle 2 tuners on one feed, I finally am up and running. However changing channels is very slow. Sometimes it takes up to 10 seconds to change channels. It does not matter if I am recording 2 shows at once or no shows at all. there is a very big lag when changing channels. Is this normal for this unit? Is there a buffer setting or something like that?

yes, normal - this is old model ( using VIA 733 MHz CPU )

It should only take 4-6 seconds.

If it is taking longer... it has old software or the smart card is having problems. It could be an lnb problem. If you just got it from someone, I would suggest wiping the software out and re-installing it.

To get your 721 back to almost the way it was when you got it...

1. Menu->6 System Setup->5 Diagnostics
2. Info->Right->Left to get to Debug Status Screen

From Debug Status Screen :

Delete all Persistent Files plus recordings.
1. Info->Down->Up

Clear NVM Ram (Settings, favorites, checkswitch, etc)
1. MT+BT Button and then reboot.

EPG Data Delete (Delete all GUIDE files)
1. Info->Up->Down

Revert to Factory Code(Actually last downloaded software version)
1. Recall->PageDown->Up

I would try those in that order and see if that fixes your problem.

Who did the upgrade to Dish Pro Plus?

Did they replace the dish and lnbs with new?

Try rebooting it! Mine sometimes does it take out the smart card and put it back in again.
