Hi WMC gurus and newbies alike... I've been trying to find a reference point for what MCUPDATE switches there are and what they do... but seems there isn't one? From time to find when something breaks I've found suggested fixed from people including running mcupdate with various switches but now I just end up trying all of them until one works in a given situation. So I thought I'd start this topic and if you know anything you can add to it... at the end I'll compile / clean it up and post the summary.

So far I've found:

The Mcupdate scheduled task downloads the following data packages. These data packages are used by Windows Media Center in Windows Vista.

• Directory Service: The Directory Service package lists the packages that are available in a region. The Directory Service package also provides information about how to obtain packages, about how frequently to download packages, and about when to download packages.
  
• Client Update: The Client Update package contains updated regional information.
  
• Sports (United States & Canada Only): The Sports package contains information about sporting events. This information is integrated with other Electronic Program Guide (EPG) information. .
  
• Net TV (United States only): The Net TV package contains information about videos that are available on demand.
  
• MCESpotlight: This package contains information about Online Spotlight applications that are available.

The following switches and possible definitions of what they are doing:

• mcupdate.exe –MediaCenterRecoveryTask brings TV setup back to factory default
  
• mcupdate –uf forces a new package to be downloaded - but which package... just any you're missing?
  
• mcupdate.exe -uf -pscn0 –dbgc full guide update & clean database?
  
• mcupdate -u –nogc

Appreciate any inputs !

-u
go out and ask the server if there’s a new package to download (even if its not the scheduled time to ask)

-uf
same as above, but forced package to download, regardless even if the package exists locally.

-pscn N
N is a number. Trigger a scan if its been more than N hours since the last successful scan (-pscn 0 is a valid input and triggers a scan)

-dbgc
perform a guide garbage collection on the sybase database, deleting entries that are no longer referenced.
-nogc
don’t perform a guide garbage collection on the sybase database, even if it’s the scheduled time. ( do not use this option, as your sybase database will grow to a point where the .NET framework mscorwks.dll!InitializeFusion thread consumes near 50% CPU utilisation when EPG is displayed )

-MediaCenterRecoveryTask
perform a guide sybase database reset ( must first quit MC )

Thanks for the contribution bigdonk - much appreciated.

Could you elaborate just a little for me...
1. does 'package' mean everything it's getting or are there multiple 'packages' (e.g. the US sports package, IPTV package, etc.?
2. what does the scan actually scan for? Is it for the guide data specifically or for packages?

Many thanks!
