Cable TV Distribution Amplifier

For digital channels or HDTV channels, unless you're experiencing drop-outs (picture freezes or macroblocking), it won't do anything for picture quality.

It might actually cause problems that jautor mentioned. Too much signal is just as bad as too little.

Yes, but if it's happening on fast motion only, it may just be the limits of the broadcast you're receiving. Dropouts from weak signals will appear as blocks of the wrong colors, garbled areas of the screen and so forth.

If your set-top box has a diags screen that can show the signal strength, go by that. You could insert the amp at the lowest gain, and raise it. As long as you don't overdrive the signal as egnlsn mentions, it won't hurt anything. But unless you're getting dropouts/blocking due to a weak signal, it won't help either.

Since you already bought the amp, go ahead and insert it, see what you get. But do keep the gain on the low side - you should shoot for a +3-6dB gain after accounting for your splitter losses.
