You can download the PortableApps.com version of VLC Media Player. It's a simple no-install executable that does everything the regular VLC Player does, except since it's not installed there are no registry entries and the entire app runs from its own folder. You can use it from a USB flash drive if you like.

Couriant: you may want to check your filetype associations. Your system might have VLC Player set as the default application to handle media files and those VIDEO_TS folders from DVDs. Go into the settings menu on your media player of choice and make sure that app is the default for your media files. In Windows Explorer, right click a media file and select "open with" to audit your default filetype associations. Choose the program you prefer, and tick the box marked "always use this program to open this kind of file." You may also want to check that PowerDVD isn't set to auto-run on disc insertion.
You can, of course, set VLC to be your default, as well.
To all:
The CBS site and HULU.COM as mentioned by a previous poster are absolutely 100% official.
