We have a Direct TV satellite dish (single,round) that has two cables coming out of into a multiswitch in the attic so we can split out to three . One to the lving room, one to our sons room, and one to the bedroom where the Tivo R10 is located. If/when the multiswitch is connected, the R10 will lose signal on some channels, or not show up at all. If I remove the multiswitch, all channels are available on the R10. This only affects the R10. I've rebooted and gone through the setup etc. but it will still lose channels if a multiswitch is connected. I'll bet there's something simple that this "non-techy" needs to fix this, but appreciate any help someone can offer.
