I have noticed in the past year or so that my xbox has gotten worse and worse at playing videos. Often they will just stop playing at random and sometimes they will freeze frame in the middle of a video and there is no way to fix it but to do a hard reboot of the machine.
I have been searching for a way to fix this by messing around in the settings but found no solution. I thought I would turn here to see if anyone has an idea of how to set it up so that the xbox will run like a boss.
Found this somewhere else:
"Settings>System
-Disable Auto temprature control/set it to a high temp so the fans never kick in at high speeds ("2% minimum, 68 degrees C/154 degrees F as max temp")
-Set [video?] cache to 256kb
Settings>Video
-Set video resolution to "1080i 16:9"
-Set flicker filter "off"
-Disable "soften" setting
-Set "Mplayer" as default player
-Disable DVDPlayer full codec support (and possible fast mode)
Settings>Skin Settings
-Disable animations
Settings.Appearance
-Set flicker filter to "off"
-Disable "soften" setting
-Set resolution to "1080i 16:9"
Settings>Network
-Disable all settings (FTP, UPnP, Control)
UPnP Sharing is probably fine but I remember he said to disable
If you need FTP just re-enable when you need it and disable when you don't
-go back to the main menu very often in order to not have a memory build up.
-if you crash on video library, it is recommended to use files mode or use ToDDS
And finally (and obviously), use a memory-friendly skin like PMIII.HD, Project Mayhem 3, JX 720, or SLiK"
