is there a list?

For example, I was watching HBO-HD earlier yesterday and it was fine, but when I watched it last nite it was just horribly compressed. What I don't remember is which HBO-HD version I was watching (77 or the higher ones, east or west). So I assume that one of these HBO-HD transmissions is in mpeg2, the other one(s) in mpeg4?:confused:

is there a list somewhere that says which one is what?

A fellow DBS Talk user made this site. Excellent reference.

It should answer any and all questions you might have.

The site is maintained by pgfitzgerald here at DBS Talk.

If you mouse over channel 509 (ie: HBO HD) you'll see the additional channels (70 and 501) that it is "mirrored" on.

I know pgfitzgerald likes to keep it up to date and as user friendly as possible so I encourage you to send him feedback.

BTW: looks like you're fairly new so in case someone hasn't already done so, welcome to DBS Talk.

why thank you! :) Yes, I'm an old timer over at AVSforum, and I'm just getting my feet wet with directv.

I'm ultra anal about PQ and hesitantly paid comcast their high $$ for their handful of HD channels because of the PQ. Now that I have the HR20-100 + OTA antenna, and done some side by side comparos, most of the channels are comparable, except these obvious MPEG2 ones......ergo my curiosity.

Paul....I must say, EXCELLENT work, so thank you!

My only suggestion right now is to list ALL the channels, and either color code the little black button with the channel number (or the entire text description) so as to show it as a "mirror" channel. Other than that, great stuff, and to the top of my bookmarks it goes.

if you guys ever need audio/video info or help, you let me know. Heck, i'll get you started with a couple of cool DIY cable threads I made for the guys over at avs:

Yeah, Paul's site is pretty cool. It is also at the top of my HDTV boomarks. :)

Looking over the list, I'm surprised at all the upconverted from SD channels there are, especially Sci Fi. For upconverted SD, SG: Atlantis and BSG:Razor looked damn nice, especially the latter. Seeing that HBO is upconverted doesn't surprise me, as I've been unimpressed with the PQ on that channel.

The listing does not mean that all HD on Sci-Fi and HBO are SD upconverts, but simply indicates the manner in which the channel handles its SD material.

There is lots of HD on Sci-Fi and HBO (although it looks better on the MPEG4 channel.)

Equipment includes a buncha stuff that I no longer have interest in detailing

Correct. Basically what those columns mean is that when the channel is *NOT* showing HD, what do they do with it (stretch, crop, zoom, etc)?
