Some HD channels blinking on and off

Not sure if this is the right place for this but is seems equipment related.

I have some HD channels (History HD, H2, FXHD) that blink on and off.

Before blanking out, the video speeds up, goes blank and then comes back on.

Sometimes the commercials are ok and the main program blanks out. Sometimes it's the opposite.

 

The Standard channels do not have the issue and neither does the upstairs tv , which is not HD.

 

I recently relpaced my Zenith 36" HD tube with a new Samsung 46" LED, with the same result

It's been happening for quite a while but I thought it was the older TV.

Also have internet working with no issues.

 

I have a SA 3100HD box using component video output.

I'm thinking it's the box, but maybe it's signal related?

 

Any thoughts are appreciated.

 

Thanks,

Dennis
