Yep I get exactly that when the signal quality is at its best. When it worsens, the pictures and audio will drop, and also the remote control loses its responsiveness. They are now recording the HD channels at the head office so if you have specific dropouts at certain points in a program you should be able to contact them and compare notes. If they have the same dropouts as you it could be the source or the receivers. If they have different dropouts than you that's probably an issue with the local distribution.
