while in bridge and I am thumbnail view it does not show a photo for .MTS/AVCHD. Is there a way to make it show image thumbnails for AVCHD videos? Same for .mpeg

it does show photo thumbnails for .AVI .Mp4 .MOV .Mpeg

Are you using Windows 7 or an ealier OS? I think AVCHD thumbnails do not display either in Explorer or Bridge on pre-Win 7 set-ups.

I'm using windows 7 pro

And which version of Bridge?

cs5 4.0.4.2

Dave, have you inquired over at the Adobe Forums for this issue?

Adobe Forums: No MPEG preview or playback in Bridge... (http://forums.adobe.com/thread/652660?start=0&tstart=0)

There, a few users mention about clearing out the cache, resetting preferences, etc... Even a clean re-install of CS5 and possibly the OS.

Hope you can figure it out and get it working for those files.
