Need help with noise on one channel

[caesar25e]

I have a pvr500 and one channel has a lot of noise. My connection is made up of a Motorola signal booster to a 3 way splitter where it then goes to a cable modem, TV and computer. The noise does not show up on any of the channels on the TV.
Any ideas or suggestions would be great.

I have posted screen shots of a normal channel and the bad channel.

That noise is usually due to an overboosted signal. You should try to reduce tha gain of the amplifier.

To me it looks like ingress. I had a problem with my pvr150 picking offair interference causing lines similar to this.
