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.

If you have noise on Ch5 & Ch2 in diagonal stripe (herring bone?), I
find that generally indicates TOO MUCH signal strength which can be
solved by using a proper 1GHz splitter w/ attenuation (2/2/4, 3/3/6).
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.
