I encounter the following situations, all with 1080i50 content. If desired I can provide samples for all of them.
- Perfectly good playing content. No problems at start of play.
- Content which shows only a few seconds distortion at start of play and when skipping back/forward
- Content which shows 40 seconds distortion at start of play and when skipping back/forward
Yes, I have, in the mean time also found samples that work.
as I initially said, for the collection of TV-providers I have and watch, at least 90% have the 42s problem.
That's why I really think this needs a fix urgently.
As i also said elsewhere, it is almost like a joke that the distortion is 42 !! secs on my machine, not 41, not 43 but 42 !!
As if someone did it on purpose :-)
Any news about this?
FYI, latest test driver 2857 doesn't show any different behaviour. 1080i50 bug remains.
test files can be found here:
If you need more, please let me know.
Just got this thru to my follow-up email to Intel support:
Thank you for sending us a follow up email.
Please be patient, this issue has been forwarded to the proper department and they are now checking the videos that you sent. As of now, no information yet if there will be a new driver but don’t worry, as soon as I have an update, I will send you an email.
Some additional info regarding the 42s bug.
I noticed that this 42s distortion also occurs if the stream has a 'glitch' (happens, with live-TV).
I have a 1080i50 recording which I can watch for some time. After the initial 42s distortion things seem OK. Then I get to the point of the 'glitch' and again it takes 42s until everything looks OK again.
Using a sandy bridge/clarkdale/X4500 the glitch is just that: a glitch, less than a second. Not so with the IB drivers.
Seems like something is taking a long time to extract some info from the stream, or just looking in the wrong place? Just a guess.
Anyway thanks for confirming that at least someone is looking into it.
A fix for this issue has been identified and checked into the driver. The driver with the fix is currently in the validation process so I do not have a release date at this time. I will post a direct link to the driver with this fix once it has been posted to Intel Download Center.
Sorry about the noob question - how does one tell if the content is 1080i50hz? I'm setting up a cable tuner/HTPC and was considering using the new Mac Mini with Windows 7 on it. I currently have Win7 installed on this laptop (also a mac) and have been able to use WMC and the tuner on that. How can I find out if any of the channels I use are 50hz to see if this would be a problem for me on the Mini?
Hopefully the new drivers will be released soon and make the point moot..
@Mike:in WMC enter 'debug mode'
e.g. tune to 'TV'-channel 411 and press OK on the remote.
If you don't have a remote, type 411 and CTRL-D.
Then you can cycle through numerous pages using left/right arrow.
To leave debug mode tune to a different channel or type 411 left/right
On one of the last pages you see the content properties incl. original resolution/refresh rate.
New drivers are out, I'll try tonight.
