FAVC doesn't install to the list of programs. When you download it, it is in a compressed format called a zip file, or you can download the .exe file. You can right click on the zip file and extract it to any place on the computer you like, or if you downloaded the .exe file just double click on it and it will extract itself to the same place you downloaded it. When extracted if will make a new folder called FAVC1.07.
To actually use FAVC, you open the newly formed folder called FAVC1.07, then click on the FAVC.exe file. That will start it up.
To use FAVC you will have to download and install AviSynth and Net 2.0 as I pointed out earlier. AviSynth will show up in the Programs list, but you don't ever have to do anything with it. FAVC will use it automatically. Net 2.0 won't show up, but again, you don't have to do anything with it, FAVC will use it.
On to DVDFlick. Unless you change the output setting, DVDFlick will save your video in C:\Documents and Settings*Your Name*\My Documents\dvd. Of course, the part that says Your Name depends on your user name in your computer. I suggest you look for your video there, in the folder named dvd.
