Home will do fine, just run Hauppauge WinTV, it comes free with all Hauppauge cards.

Again, this is only for testing purposes, we need to eliminate variables in order to determine the root cause of the issue.

EDIT:  Updated the video driver to the latest in Win7; no change.

Ok, checked the tuner driver version in XP and it was the same as I was running in Win7 prior to upgrading yesterday, so I rolled back.

I also rolled back to the same nvidia drivers in Win7 as I was running in XP, but the corruption still exists.

Next stop: Fresh Win7 x86 install

Interesting description above about pixelation on the bottom half of the screen only.

That's kinda what I'm seeing on my system when I use the 30 second skip. Sometimes pixelation, sometimes a refresh issue like a poorly encoded rip without enough key frames: ie only the pixels that contain movement are updated.

In either case it's only for a second or two then comes right.

This is on a freshly built machine with Hauppauge 2200 and Intel G840 CPU, Win7 MC. I had thought it was a performance issue with the G840's integrated graphics, but having read through this I'm not so sure.

This may help you go into catalyst control panel and turn off all video enhancements but particularly enforce smooth video .....

Depending on what codec you are using you can get a conflict between the code in ATI drivers and the codec that attempt to playback video smoothly. This can actually make it worse.

Try it and let us know if it solves it for you.

Yup, that's pretty much what I get as well.  Generally this only happens on the lower half of the screen tho, which is quite odd; you'd expect corruption like that to affect the entire frame...

Turned off everything and still have same problem.... I had disabled most of it already anyway but enforce smooth playback was still on.

It's sad to see ATI still can't get their hardware and drivers working 3 1/2 years after first being told about the issues. NZ's not even semi unique in terms of H.264 now.

It's really a shame because the new AMD Fusion mobo's would make a nice HTPC upgrade, I'm just not sure if I want to take yet another gamble on ATI.

mm1352000:
The fact that your problem seems to be system wide and that the NV card made a difference makes me think video card, but it could be a number of things in combination. I'm using Catalyst 10.4 with my HD 4670. 
mm


Just completely uninstalled V11.8 Catalyst package and installed V10.4 This has an older red ATI logo in the system tray.

Early days yet, but immediate obvious improvement. Skipping through the pause buffer on TV3  FreeviewHD (UHF) and there is no pixelation or stutter. Yay! Resynching of video with audio after skipping isn't quite instantaneous, but it's not breaking up or stuttering like it was. 

Nothing else has been changed only catalyst driver back to V10.4. http://support.amd.com/us/gpudownload/windows/10-4/Pages/radeonaiw_vista64.aspx?&lang=English

Will reset my preferred tuner order in MC and just Watch TV for a couple of evenings. I'll keep you posted.

Regards Allen.

Edit: Watching the Credit roll on Titanic and they still arn't as smooth as they should be. It's either dropping frames or has some timing issues. It's pretty subtle and was  not noticeable during the move just the credit roll. It's more noticeable when mouse/keyboard focus is taken away from media centre onto my other monitor. I guess media centre priority changes when I do that. I have increased the priority of media centre processes ehshell & ehreciever to high but it made no difference

They've fixed it and broke it again multiple times in different driver revisions, it's weird.

Is there a newer version than 10.4 where H.264 works properly?

the versions I have installed with Catalyst 10.4 are

Driver Packing Version 8.723-100406a-098769C-ATI
Catalyst V10.4
Provider ATI Technologies
2D driver is 8.01.01.1016
Direct 3D Version 8.14.10.0743
OpenGL Version 6.14.10.9756
CCC version 2010.0406.2133.36843


By the way I have never updated the BIOS on the card is this possible or neccassary or should I leave well alone?

Asus EAH5770 (ATI Radeon HD 5770)
Bios V 012.020.000.004 31/3/2010 

Regards Allen.

Intel has their own problems when you use HDMI. If you're using the GPU in new CPUs then try the driver recommended at the end of this thread.

Now you know why I stay on 10.4. I just don't need the headaches.

AllenG: Is there a newer version than 10.4 where H.264 works properly?

Like I said to you in my first response, the versions since ***11.4*** have been bad (ie. 11.4 is the last known good version). You responded and said you'd tried 11.5, 11.6 and 11.8 - all bad. Did you not read what I said carefully enough? Wink

Thankyou mm for pointing out the error of my ways. Embarassed

I took more notice of your endorsement of V10.4.

If 11.4 is good, why have you stuck with 10.4?

Allen.

I'm reporting second-hand info. Problems starting being reported with 11.5 and the standard resolution in all the cases I've seen has been to roll back to 11.4.

[Edit: to be clear, I'm a member of the MediaPortal development team and I am quite active in providing support for a range of issues on their forums. ATI driver issues have been a bit of a pain recently...]

I stick with 10.4 because I value stability over performance. I spent days if not weeks experimenting with various versions when I first got my HD4670 - as I recall 8.12, 9.1, 9.2, 9.3... etc. - trying to find a version that worked with DxVA on Windows XP, which was a major problem at the time. When I eventually found a stable version I decided to stick to it unless there was very good reason to upgrade. As of right now I haven't found any good reason to upgrade more than once (from 9.4 to 10.4). When things work ATI is fine, but they seem to have a terrible habit of periodically breaking things badly for HTPC users in the interests of getting performance for gaming users. When that happens, they usually spend 3 or 4 releases trying to patch up the mess they've made and regain the confidence of their HTPC users. As I say, I'm totally not interested in performance. I just want a release without too many bugs that gives me good DxVA support, no black level, contrast or colour issues, no sleep/hibernation issues, and generally just works.
