tried that too.. they didnt work from a clean install with only the x64 win7 codecs installed.
i can't understand why it's just me this is happening too!
do your avi thumbnails work and if so which codecs did you use?
thanks for all the help so far guys!
Personally I use MP3TagEditor to change all of my video files to static images of my choice (i.e. DVD covers) - i'm sure you could probably use that to select a specific frame of the video as your thumbnail as well.
I also highly endorse the Shark Win7 codec pack beta; it's enabled me to view things like m4v's and mkv's (and also generated thumbnails) where it hadn't done so before. If you're using Win7 x64, be sure to install both the Win7 codec pack and the x64 component add-on package. I still haven't figured out whether I like using Media Center in 32-bit or 64-bit mode better yet, but these installs make it easy to switch back and forth, and to change codecs for certain filetypes.
Mine's doing the same thing, even with codecs installed and even in the 32-bit explorer. (Running x64)
Here is what mine looks like, as you can see some are black, but they also start off black for the first couple of seconds.
That's the same problem as me! Some frames at the start aren't completely black but still, isn't windows supposed to choose the brightest frame from the avi file for thumbnail generation? Glad to see it's not just me with the problem.
no more ideas guys?
i've noticed something interesting... it could just be that these videos all start with non-black frames but look at the screenshot below... the thumbnails for the videos on the right seem fine... they are about the only ones in my video library that are!
wierd ey??
Now that is strange, did you also notice the dimensions of the preview differ from the ones showing no previews unlike the ones I have that are blank that have all the same dimensions, just out of interest can you move those AVI's to the folder showing previews to see what happens.
i think it's because the unit is broadcast in widescreen whereas that season of family guy is not!
there was no change when i moved a family guy episode to the folder showing thumbnails
