Try the following scenarios: 1. An underpaid Radio shack sales person once told me that if you have multiple splits, it makes sense to put a terminator on one of the unused ends from a split to prevent signal degradation. 2. I noticed that sometimes an FM signal eliminator removes some interference a cable with low quality shielding receives from the air.

Though 1GHz if what's needed by the cable modem & digital cable, since you're talking about problems in the low end of the analog signal it's likely not a 900MHz vs. 1GHz problem (not that you shouldn't use a 1GHz but those channels came over 900MHz splitters for decades). Which cable modem do you have? The Motorola's have a nice feature that a status page shows the signal strength coming in. It should ideally be 0db/mv, higher would cause the kind of problems you speak of on Ch 2 & 5. You could use that to decide if maybe you need higher attenuation to the TV feed.
