You often see macroblocking on sports - basketball on RSN at times is particularly bad and it was also noticable last year on CBC during the heritage hockey game - one time the camera was focused in a picture far away and a player skated in front of the camera taking up most of the field of vision of the camera - major, major macroblocking.

The diving in the Olympics this past summer was also very bad.

Cool

Still Macroblocking...Just called into Rogers to ask about this issue - was watching BB2 and couldn't bare to watch it anymore. The TSR told me the signals on my end were great and that they would have to look into it on their end and would call me back.

I have been noticing this effect since I got my TV a few weeks ago and wondered if it was the TV itself. Good to see it seems like all models are having the same issue (well not good, but you know what I mean )

I'll post any feedback when/if I hear back.

Bad Boys II also has plenty of bad moments. I figured it was just the 19Mbps problem with a lot of "Bruckheimer flash".

Otherwise TMN-HD PQ is outstanding - source permitting of course. Check out A View From the Top some time

57,
Her'es another movie that had way too much macroblocking: Paycheck.
The movie would go fuzzy at times also. It had a hard time with fast moving pictures as well as reds flashing.

Now that's odd because I just wached Paycheck off the PVR last night and was going to post that I found little or no macroblocking! There was also very little 'pixelation' on this particular recording, thank goodness.

I'm with Rogers. You?

I recorded Paycheck, but have not watched it yet - will advise when I do. I watched Cold Mountain and it had major pixellation/sound dropouts and one "freeze frame", but no bothersome macroblocking.

I have also noticed that the macroblocking is more noticeable with "reds".

I have not heard back from TMN on this issue - probably on holidays or working on the issue. Will advise when I hear back.

Danster is with Rogers NB, Motorola STB.

During a bowl game yesterday, ABC had one of those "sweeping logos" that goes across the screen following replays. During the olympics, the NBC sweeping logo had major macroblocking. The one on ABC yesterday was "clean".

That reminds me...I watched Cold Mountain 'live' a few days ago...no macroblocking, and of course, no pixelation or drop outs.

The spot that had the most was when Affleck is interrogated by the FBI on the chair and then the guy lights up a cigarette, hell breaks lose and all. At that point, when the reds flash, it looks like a Tetris game going on. Many little weird shape blocks appearing and dissapearing. A bit like Pink Floyd the Wall type of uneven blocks.

Yeah, just re-watched that segment and you're right. I've seen worse, but that's pretty bad.

Watched "Badder Santa" last night (or most of it, what a bad movie, kept waiting for it to get better, finally FF through about 1/3 of it). For the 2/3 I did watch, I encountered little pixellation or macroblocking.

I FF to the "red segment" of Paycheck (haven't watched it yet). There was major macroblocking at that "red" segment.

I find that if you FF, due to the "freeze frame" nature of FF, that you can find the macroblocking quite easily....

I also watched Discovery Channel's "Ultimate Cars" in HD. There were two programmes. One was on "top 5 peoples' choice". There was absolutely no pixellation for that 1/2 hour. The other programme on "top 9 cars" had several pixellation issues as well as macroblocking. It's so odd that some programmes are "clean" and others are "not".

My drive was about 70% full at the time of viewing both programmes. Most of the time my drive is less than 50%, but I just got back from vacation and I'm catching up...

I actually watched Badder Santa too last night. I found the dry humour quite amusing! I did notice minor, but relatively frequent, 'errors' in small parts of the image all during the presentation.

57,
Here is another one: Stargate Atlantis last night.
At the point where they are chasing a Wrath ship around and away from Atlantis, the ship seemed like it was slowing down and getting fuzzy. All of a sudden, it froze in the air, blocks everywhere and the picture looked like if I was seeing it through a foggy window. While this was happening, the sound was still perfect. Then the picture unfroze and everything went normal again. It was the first time I noticed artifacts and stuff during Atlantis since last August.

Here is what I can tell you from TMN-HD.

Quote:
TMN-HD have seen the same macroblocking that we have seen, and are looking into ways to improve the picture quality...
I believe it is a good sign that they acknowledge that the issue exists and that they are willing to look into improving the PQ.

57, feel free to delete this post, but I did not see Danster's issue on the new MC-HD. Would not TMN-HD and MC-HD use the same source?

It is nice indeed that they are listening. Each time my wife and I sees macroblocking, she tells me "Are you going to report it to the digital forum again?".
I looked at 280, the ROGERS prevue channel when they show the football loop. There doesn't seem to be any pixelation as far as I can tell.
No matter what, thanks for bringing it up to your contact.
