View Full Version : why do my HR20/H21s have worse picture quality than my old HR10?

I had a HR20 and two HR21s installed last month, because DirecTV gave
them to me for free. The three HR10s were removed and used in other
rooms of the house.(SD only, on old SD TVs)

Last night, I took one of the old HR10s and plugged it in next to the HR21.
I unplugged the HR21's HDMI cable and connected it to the old HR10.

The viewing was done on a new Panasonic AE2000 1080p projector,
using a Da-Lite High Power 133-inch screen in a completely-dark
basement room with dark walls.

The output of the HR20/21 and the HR10 were all set to 1080i. All
I did was unplug the HDMI cable from one to another, so I could
compare them objectively.

Wow.... I thought there was something wrong with my eyes when I
immediately noticed how much better the picture was. The HR10's
output was clearer, sharper, and the colors were a little more vivid.

I played back several identical programs that were recorded
both on the HR21 and the HR10.(example: Rick Steves European
travel programs, several movies on UHD, and documentaries on
Discovery HD Theater) Obviously I can compare the channels in
the 70's, which are MPEG2 that the HR10 can record.

Don't the HD DVRs(HR10, HR20, HR20) only receive the DirecTV HD
signal and sends it out via HDMI? Or is there some sort of encoding,
re-enconding, or decompression going on inside? That's the only
possible reason that I can think of... otherwise, I can't figure out
why all three of the HR20/21 have worse picture the the old HR10.

Oddly, I notice very little difference when I conducted the same test
on my living room TV(a Panasonic 58" 1080p plasma, ordered from
Costco.com) Perhaps the much smaller screen hides it better?

Is there a remote chance that all three HD DVRs(2 HR21s and 1 HR20)
are somehow defective? The DirecTV retention dept rep that I spoke
to that they'd be happy to send me out a replacement with a return
label... I'd like to figure out what the problem might be before I do this...

Thanks for any info! :)

I had done a similar comparison between my HR10-250 and my HR20-700 on a Sharp projector at 92" and was more impressed with the HR20-700 than the HR10-250. I noticed a lot of noise in the picture from the HR10-250 versus the HR20-700. I did that way back in August though, before the new satellite was on line.

Hmmmm, strange. Most people report the opposite that the HR20/21 offers a better picture.

But then picture quality also has a lot to do with calibration of the TV set in question. Perhaps on your big screen the difference between the 2 is enough to notice. Try and calibrate with the HR20 in mind and see if that helps.

I guess my rather puny 37" TV isn't adequate for this level of comparison.

Isn't Tom picking you up one of the 150" Panasonics at CES ?

Seriously? Do you really expect completely different boxes to look exactly the same? :confused:

Every box I've ever owned, DirecTV, cable, Myth box, etc has always required that I re-adjusted the TV to match the particular output 'flavors' of the box. You don't really have to 'recalibrate' the TV, just adjust the normal settings to match what you're getting.

These aren't toasters...
