SA 8300HD DVR Noise and Blackout Problem

I recently moved to an area and had to switch from Comcast to Cablevision, and i am still trying to get used to the new 8300 hd dvr. Here is my question and this has happened twice. I went to watch a show that i recorded in HD, and when i turned on the program, i was getting a crackling noise every couple of seconds. Every time the noise hit, there was a shard sound, the volume changed, and the picture would black out for a split second. It made it hard to watch the program. It would happen at random time, but it is constant and every couple of seconds. I have the unit hooked up to a panasonic plasma, and a sony KDS-R60XBR1. They are both hooked up with componet cables, that have been split. I tied unsplitting them, and i have the same problem. Both tvs are hooked up with a/v cables for sound, one comes from output 1, and the other output 2. Both tvs exhibit this problem, so it is not the TV's, it is coming from the 8300. I have watched about 2 dozen hd recorded programs, and this has happened now on 2 different shows. Any ideas?
