I have just installed the RC with an ATI3450

This card worked fine with Beta 7000 and it works fine in RC on our progressive channels (H264).

However with our interlaced channels (H264) I am getting a black screen with an occasional block green display.

I tried the latest ATI drivers instead of the windows ones with the same result.

Any ides?

If you've followed many of the threads here on GZ (and elsewhere) over the past year you'll see that there are well known issues with ATI video cards and interlaced H.264 video with hardware acceleration.

Most people don't get this working properly and have issues with green pixelation.

I have seen the other threads. However this worked fine in BETA 7000. Something has changed in RC.

Just a note that I installed the ATI drivers from B7000 and the problem stayed so it may be a bug in RC rather than ATI.

I have the same problem in 7100 with an ATI 3450. Interestingly I can tune tv3 fine, plus the 720p channels, but the 576i channels all give audio only with a green or very pixilated image. I did not have this issue in the 7000 beta.

Hi All

I gave up waiting for ATI and bought a EN8400GS passive for ~$80. Now the interlaced channels work. It also is much smoother when you skip through a show.

It does not have HDMI but I use VGA anyway. The latest Windows update added support for 1360x768 at 75hz which looks great on the tv.

Effectively it does have HDMI. DVI=HDMI-sound. You just need either a converter or a DVI to HDMI lead.

I know what you mean but the ATI card I had did sound and video over the HDMI.

@sbiddle's original post, i think you're a bit out of date re 1080i, h264 and ATI, been working fine here for nearly a year!

There are people who have posted both here on GZ and elsewhere are running ATI systems and have no troubles at all.

There are also large numbers of people both here on GZ and in places such as the DVBViewer and Media Portal forums who still encounter these issues.

The problem is anything but fixed entirely - it should just work fine for everybody like NViia does.

Large numbers of people? The silent majority i would think are fine. Most green block problems were erroneously blamed on the ATI chipset when in fact it was a PDVD8 codec issue.

The issue that I raised with ATI is different to all the old ones. Also the problem only appeared in the release candidate - it worked fine in the BETA.
