Look at text. And at crowd scenes. There is noise on the text and crowd scenes (like the Pocono commercial) on the MPEG2 version that is not there on MPEG4.

ESPN will never be perfect (as I see some of the same mess on cable as on DirecTV) but when it was messy, it was messier on DirecTV than comcast (things like crowd scenes, blimp shots, high action). This should clean it up. I can see a difference for sure. The clock in the lower right pops off the screen, for example.


Have you got cable and DirecTV? :scratch:

Yes. I have a cable modem and the pricing here means cable TV is a marginal cost. It also gets me locals from DC (condo so roof antenna not possible). I use an HD Tivo for that (see signature).

I have both a HR20-100 and HR10-250. On my HR20 I can definitely tell a difference between UHD 74/259. However on my HR10-250, 206 and 209 are both still working. ??


On the hr10-250, you can only recieve SD versions on 206 and 209 you have to tuen to 73 and 74 to get the hd versions of those channels...

do you have your box set to 1080i output only? i have found that a cable or D box converting 720p to 1080i causes artifacts on motion, thats why mine is set to output all resolutions and i let the tv do the conversion and scaling.

mines is set to native on and all resolutions are checked. I still don't necessarily see a difference between 73 and 206. It looks good and all, but i just don't see the difference. I'll wait til ESPN broadcasts a live game and then take a look.

I am seeing a large difference now that I can compare the MPEG2 and MPEG4 signals. I think it's not just the compression that was used, but that fact that the encoder being used on the MPEG2 channel is ancient. I am suprised at how much better the MPEG4 works, considering this is a 720p source.

I am getting Searching for signal in Houston on 206 and 209. I have an H20 and I have an HR21. Neither one can get theses channels. I also am not getting TNTHD or HD Theater.

Do they broadcast in 720p or 1080i, and does it make much difference how you set the HR20. I have Native OFF and set to only 1080i.

Looks like I can't see the new satellite. 99c is absent on my H20 and my HR21 sees it but signal is only in the 40s'.

I am disappointed. The Scores as the bottom of the screen look that same as it did. It doesn't look any clearer to me at all on my H21 Receiver. I can flip over to channel 73 and it looks the same to me.

Low signal on 99c here, no ESPN or ESPN2 in the 200s, among other channels I'm not getting as well.

When I turn on Channel 206 and compare it to channel 73, ESPN Looks the same on both channels for me. I can tell no difference from watching the Cubs @ Brewers game from last night.

Since this thread was at the top of all of the other transition threads I'll post this here. May I suggest that all of the MPEG2 -> MPEG4 Transition Discussion threads be put into a subforum of their own.

Ok so for the channels in the 70 range, are those still mpeg-2 and the ones with 3 digit assignments -4? Or do the older channels automatically map to -4 signal but keep the same channel number?

For example I was watching Sportscenter on 73 this morning. Was I watching the -2 or -4 feed?

73 is MPEG-2 and
206 is MPEG-4 from D11.

There's not a big difference, but it's there, especially in studio shots. Their studio cameras were always a bit noisy, and the MPEG4 minimizes it. IMO, ESPN2HD has a bigger improvement.
