Many thanks for the reply.

OK my setup is as follows

Setup
Dell XPS710 PC with Core2Duo, 2gb ram, 1.5TB HD, Vista Ultimate 32bit with Vista Media Center, Media Player 11 (shares setup OK) latest CCCP codecs and reg. hacks..
- PC is setup with all tweaks and registry hacks so that VMC can see AND play avi, ALL movs (SD and HD resolutions), Divx, xvid, .ts files (i.e. blu-ray and hd rips). In fact everything plays. The only thing I cant remember is .mkv format (thru VMC that is)

Xbox360 - has latest updates, connects to PC via Media Center and natively via Video dashboard.

All above is connected via hard-wire ehternet Cat6 cable and performace is superb.

I have many movies in true WMV-HD format in resolutions 720p and 1080p which play without a glitch.

Problem

Now back to the original question, why can i playback high-res .Movs via Xbox360 when they are renamed to .avi format?

Whats making me scratch my head is why i fail to see any .mov and .mp4 files in Xbox360?

When i had this issue in Vista MC, all i did was add a reg_sz entry for .mov called perceivedtype.

You guys are on the ball with this stuff, so any help appreciated?

Let me ask the same quesiton in a different manner, can the rest of you see .mov formats in Xbox360, either dashboard or media center?

cheers
