Having gotten the new software update for my hr 21-100, I've noticed that there is a complete reversal between the audio on sd and hd channels. Before,the clarity and loudness on the hd channels was far superior to sd broadcasts. Now, it seems that sd is much louder than hd. I've had to turn the volume way up on all hd broadcasts to compensate. Is anyone else experiencing this? I know I'm not imagining this change!
