I recently upgraded from Vista Ultimate to Windows 7 Ultimate (x64). I had some playback issues with certain AVI files & so downloaded the Win7CodecsInstaller (Shark 007). I was hoping that this codec pack would also restore my FLV thumbs, but no... And so, I just installed the K-lite codec pack (v. 5.4.4, Full) to see if this would solve the problem. During the installation process, I carefully looked for the setting option to "make thumbnails possible for the following file types" (with FLVs included in the list), but it never presented itself. (Perhaps this is now just part of the default settings?) I still have no FLV thumbs: all it did was to change the icon from one generic image to another. I would be very grateful if someone could help me with this issue. Many thanks.
