refresh rate and theater mode issue

[Dima]

Hi,

I'v been using HD 2400 Pro PCIexp on XP without any issues.
Upgraded to Vista 32 (fresh install) and now got the following problems.

My monitor's (Samsung 755DF) refresh rate drops from 85Hz to 60Hz as soon as
I enable TV-Out.
Forcing it to 85Hz doesn't help.
Removing auto identification and setting manually to 1024x768 85Hz doesn't
help.
It was in clone mode.
Set TV to extended mode and now monitor works fine at 85Hz! with the TV.

Now theater mode will not work. I set it to theatre mode, and nothing, TV
shows the same thing, or extended mode, but no full screen for movies.
I tried goggling the issue but came with nothing.
happens with 7.12,
will be trying older versions, but I was wondering if anybody encountered
the issue.

Thanks for any info.

Didn't get any answers...
Just letting you all know that I fixed the problem by going back to XP on
that HTPC.

Theater Mode did work with Vista in Media Player Classic when set using
overlay.
