I'm a programmer, and I sometimes do multimedia development, but I'm being
baffled by what seems like a user-level feature regression in Windows MCE.

I have a Vista MCE box running Vista Ultimate 32-bit on a Mac Mini (Core
CPU, Intel 950 graphics). It's been running fine for several years.
Generally, it's used to play MP3s and DVDs from a SMB shared media library to
a HDMI connected 16:9 flat panel.

After the latest Windows Update, the DVD playback has gone bonkers.

Material that is 4:3 will be scaled to fit the full width, which will crop
the top and the bottom of the image, which in turn means that subtitles are
not fully readable.

Material that is anamorphic 16:9 will be scaled *only heightwise* so that
top and bottom is cropped, similar to the 4:3 case. This means that aspect
ratio will be screwed, and everything is tall and thin, in addition to top
and bottom being cropped.

As I said, the only thing this box does is serve as a media player, and this
has worked fine for ages, with the same material that's now being screwed up.
The only thing that happened in the last week was a Windows Update (plus I've
rebooted again, to see if the problem would go away).

So: was anything changed in the MCE playback path that would cause this? Is
there some registry setting that will change this? Does it happen to all MCE
installs, or is it device dependent?

If there's a better place to ask this question, please let me know.

Haven't heard any other reporting this issue, however.....

Is this problem permanent or is it more of an annoyance when the DVD begins
and can be fixed by changing the Zoom option?

Any chance one of the recent updates was video card driver related?

Have you tried uninstalling updates or rolled back with System Restore, to
verify that it is the recent update causing the problem?
