29/59 "bug" seems to be fixed
I just noticed within the past week that I am getting a constant 59 Hz on every channel. No more jittering! Has anyone else noticed this? I'm curious if this is a widespread "fix" or something has changed only in my area. Somebody had to have done something to fix it... Comcast? SiliconDust? Microsoft?

You know where these data come from, right? They come from Comcast.
The tuner has ZERO affect on the signal; it merely passes the stream along. Microsoft similarly does nothing more than take the stream of data and puts it to disk.
And everything you see, right, wrong, or whatever, is simply the data stream.

Nope, still there (on extenders, at least)...jittering/shaking on logos static images on 1080i material (ie CNN)DOS4EVER wrote:I just noticed within the past week that I am getting a constant 59 Hz on every channel.

Makes me wonder if Comcast did something in my area that fixed it.

Yes, on multiple channels that I know had the issue, especially DRM channels like HBO. I am now getting a constant 59 Hz on each. Can't explain it.STC wrote:It's a technique used to reduce bandwidth. I doubt they would stop using it. Have you tried 411 info on a live channel?
I'm uploading a video to Youtube now to show that it is constant at 59 Hz.

If they do that to reduce bandwidth then why don't we notice the jittering and such on Tivo boxes or even Comcast's own boxes?STC wrote:It's a technique used to reduce bandwidth. I doubt they would stop using it. Have you tried 411 info on a live channel?

You're lucky, it looks like for whatever reason Comcast in your area is not doing the variable frame rate encoding any more. Are some of your channels going to MPEG-4 as well? If they already have maybe that freed up bandwidth for the MPEG2 to not be variable rate. Or, perhaps they have done this in preparation for taking those channels to MPEG4 encoding.

I was thinking about that myself, but so far every channel I've tested still shows MPEG2. Maybe, like you say, they are getting ready to switch.stuartm wrote:You're lucky, it looks like for whatever reason Comcast in your area is not doing the variable frame rate encoding any more.

Because those boxes use video hardware that can reset their processing at the frame rate change fast enough to not have it be visibly noticed. That is why the workaround/fix for WMC is to disable some of the extended processing that most video adapters do. On PC hardware some adapters can be reset in time for the effect to be not really noticeable but not always and it depends on the particular hardware. (e.g. this is why I use Nvidia lower end adapters in my HTPC's as they handle the frame rate change fast enough that it's not really noticeable to me)DOS4EVER wrote:If they do that to reduce bandwidth then why don't we notice the jittering and such on Tivo boxes or even Comcast's own boxes?STC wrote:It's a technique used to reduce bandwidth.

Ahh, that makes sense. I use Nvidia too because it did a good job with the framerate issue as I only really noticed a little jittering in logos and such.stuartm wrote:Because those boxes use video hardware that can reset their processing at the frame rate change fast enough to not have it be visibly noticed.
