Hi,
This is a persistent problem and only appears when I unselect the "Use Windows Media Player engine for playback when possible" option: All my movies appear pixelated when played. Blocky is not the exact term as it implies artifacting, at least to me. These appear terribly aliased -- the edges of characters and props appear way too jagged. I am using the Vista Codec Pack but this error was also present when I used the KLCodec pack, on a previous install.
The aliased look disappears when using the Windows Media Player engine but now it's itching at the back of my head as to why not otherwise. Another thing: I know there is supposed to be an option for an advanced renderer of some type for Vista (as I saw it in the earlier install) but I am not seeing it this time.
I am going to uninstall this codec pack and try the CCCP. Meanwhile, if someone can take a look at this issue and suggest a remedy, I would be grateful.
SPECS
Media Center 12.0.301 (why isn't this linked on the site's download page btw, considered unstable? In which case could you list it as an option there and indicate its under-development status please?)
Windows Vista Ultimate
Nvidia 6600GT 256MB
EDIT
Almost forgot -- I also don't get any sound control through Media Center while playing movies. This is true even while using the Windows renderer. Sound controls just fine while playing music files.
Thanks
