Problems with NAD Receivers????

I have an NAD T762 receiver with which I am having problems. The unit takes a few seconds to lock onto the digital sound of my satellite receiver when I change channels. Sometimes it never does. I have rumblings that many units are flawed in this way, but have not found any concrete evidence. Has anyone else had or heard of these problems? Any solutions (other than using the analog output ion the satellite receiver)?

Also, when I play a CD by using a digital output, the NAD receiver misses the first couple of seconds each song while it locks onto the digital signal. Is this common?

I have reset this unit a few times and these problems still occur.

Thanks, everyone!
