I have 4 Series 2 direcTivos that I'm being forced to upgrade to 6.4a to get locals back. I had been noticing for a while that when rebooting I would get an error acquiring the sat info. It was that it was unable to get a signal from the 110. After upgrading one to 6.4a, it took three times through the dish setup before it skipped the 110. I replaced the 4x8 multiswitch a while back with a powered model and that seemed to help for a while. I then took out the multiswitch and connected one Tivo directly to the LNB to test, but that didn't help at the time. Oh, I have a 7 year old oval triple LNB dish. Is it time to find a new LNB? The problem isn't too bad during the night, but it's aggravating after a power blink during something you were recording, especially if you aren't around to tell it to go ahead and watch the available channels. Otherwise, you lose about 15 minutes as it times out the menus.
Another issues I've noticed is that 6.4a will sometimes reboot when it loses signal during a storm. Then it has a really hard time acquiring the sat data since that's what provoked the reboot in the first place, so we're back to taking a while to get back online.
Thanks in advance for info,
