I use it all the time --- do you have any specific questions on it?
You can convert the DVR-MS to WMV; it takes 1:1 (a one hour show takes about an hour to do on an AMD 2400). Let it run overnight and you'll never worry about it. I just map a drive to where I want the WMV files to go, select all the DVR-MS files on the hard drive, and let it go. The next morning all my shows are done.
