We have digital cable from TW in the Raleigh, NC area, and they don't seem to mind you splitting cable inside the house. They readily admit, however, that you won't be able to obtain a useful digital signal if you split the feed more than twice (for a total of three outlets). As a solution, they offer a "digital cable compatible" amp for about $50. My tech said you could get the same thing at radio shack, and that is exactly what I did.
The set-top box has a nice diagnositic mode (channel 999) where you can check out the signal strength of the forward and reverse data carriers. The color of the signal strength indicators changes when they reach recommended threshholds, and so it was easy (and rather interesting) to play with the amplifier and splitters.
Remember that you need to buy bi-dir splitters which are rated up to 1 Ghz (also available at radio shack).
