and Sd hours, is it significantly mreo then the HR 20 or is it about the same?
Do the ratios: the HR20 has a 300 gig internal drive, the HR21 has a 320 gig. Thats less than 7% more capacity.
(And no, it's not really noticeable in practice - see my signature).
Well, it's not going to be significantly more, but you have to also consider that the full capacity of the hard drive is not available for recordings. A portion is set aside by DirecTV for various uses. And I don't know for sure either way, but that portion might not be the same on the HR21. In any case, I don't really think it's significant if those hard drive sizes are correct.
They will have the same recording time
It's more, whether you agree or not. I have an HR21-700, and have validated it myself...not much more, but more.
If the real question is how can it be more, then use of the eSata port for an external drive is the answer. It's virtually the same as the HR20 series, and some have used up to 2 TB units with it, giving exponentially more recording time.
Basically the same.
HR21 = HR20 - ATSC
Isn't the answer:
the HR21-700 has the same size hard drive as the HR20-100 which is 20 gig larger than the HR20-700.
Which nets out to a "possible" depending on content, 5ish hrs more of MPEG-4
Actually it's 10% more recording capacity. Since about 100GB dedicated to D*, that leaves 200GB on the HR20-700 vs 220GB on the HR-21 or HR20-100 for recording. That is a 10% increase.
Where did you get your figure that 100 gigs is dedicated to Directv's use?
Don't remember exactly, here I am sure. However, all of my math leads me to believe that it is correct. I will see if I can find out where that number came from.
