Watching Yanks/Sox and it is smooth as silk...FINALLY! ...and just in time for the postseason. I had experienced the "jitter" as recently as last Sunday and even may have noticed it on "so you think you can dance" early this week. Looks great now though!

I am not aware of any settings changes so I can only guess that they updated the firmware on the boxes?

The stuttering problem appears to have been fixed. It just took two weeks of football to solve the problem, lol. More proof that no one watches baseball.

Yes! It looks like baseball is fixed, but someone else said that baseball seemed to have been fixed last week, but football tomorrow will be the final test. Not sure how there could be a problem on one and not the other unless it is a problem with the actual broadcast and not on the cable system end.

Uh oh. Having problems here now during the Yankee game. Pixelation, frozen, and reverting to 4:3 screen size. Looks like there might be some more ironing out to do.

OTA with Vizio tuner and problem is gone. I guess Fox changed something.

At no point in your rambling, incoherent post were you even close to anything that could be considered a rational thought. Everyone in this forum is now dumber for having read it.

Most encoders default to the former or something similar with 2 max consecutive B frames. As far as I know, 3 consecutive isn't disallowed by ATSC, but it's not commonly used in any MPEG2 application. Improperly designed decoders may not handle this correctly, resulting in the stuttering seen on SA boxes and Vizio TVs. Simple workaround is for Fox to change the GOP structure in their encoders to match the one used under the old encoder.

GOP structure coming from Fox as of last night was back to the old BBIBBPBBPBBPBBP. Coincidence? I think not.

I was bouncing around from different sports but the times I was watching the RedSox do their impersonation of grass and the Yankees the lawnmower there was no problem. Aside from the Fox usual softness.

Seems like Baseball is fixed - thanks whomever. We'll see about Football....

Seemed to be fixed down here in South Florida also (Comcast, SA8300HD). Hopefully we get the same tomorrow with the NFL.

This is unrelated to the stuttering, and not found on a national basis. So the old chestnut 'local issue' is applied.

You get extra credit for that one.

Ticker on the pregame show looks much better for me, although the whole image looks blurry and crappy, but that seems to be "normal" for the Fox pregame show.

Same here. Giants game is nice and smooth. Fox has never had the picture quality of other networks though.

I have an HD-non DVR box with Bright House in Orlando and there was no shuttering during Yanks-Sox yesterday and non for Giants-Bucs.

Picture still not as good as CBS or TBS but it's a huge improvement.

I'm happy.

No stuttering on the Falcons vs Pats - but I see lots of edge pixelation on the players as they move - not macroblocking but more like jpeg compression artifacts for an overly compressed picture.

I'm watching FoxHD, channel 705, San Diego TWC.

Looks like there was some sort of tradeoff between fixing the stuttering and picture quality, cuz in the past - for me - the PQ was actually pretty good.

FWIW,
Erik

Of course CBS will look better than FOX because it is 1080i with 18 mpbs bandwidth without subchannels. CBS HD blow away everyone else regarding picture quality and sound. Thank GOD the superbowl will be on CBS on FEB 2010.
