Here's the one problem I have with audio.....and I have a HR20-700 and an HR20-100. When I review something that I'm watching live and then hit FF or advance ahead to catch up with the live programming, the audio begins to drop out every several seconds. If I hit 'pause' and then release, everything is fine again. But I shouldn't have to be doing this....and it is occuring on both receivers. They really do need a 'live' button because this whole business of FF to the live broadcast and the dropouts is bothersome.
