Also, I thought I'd share an e-mail I received from Advanced Technical Support about the 921. Here it is:
Thank you for your e-mail. We currently do not have any information
concerning MPEG-4 compression and backwards compatibility of receivers.
Stay tuned for more information as this becomes available.
As to your second question, Name-Based Recording has just been rolled out on
two of our receivers. At the current time, only the DVR522 model and the
newly released DISH Player DVR 942 (just introduced two weeks ago at the
Consumer Electronics Show in Las Vegas, Nevada) have this technology. That
is not to say the model 921 may not have this software in a future software
release. Once again, stay tuned for more information as this becomes
available.
From researching the hard drive noise issue with the 921, it seems this is a
normal occurrence. If it is gradually getting louder or is disrupting
programming, I would call in to our technical agents and have them
troubleshoot this issue. The hard drive on the 921 is over four times as
large as that of your 501, so we can expect it to make a little more noise
as it is spinning.
Sincerely,
David
