After the latest update (colored icons), there are now a number of sites I cannot seem to download 'valid' videos.
They seem to download, they appear to have the .mp4 extension, but they will not play in Quicktime or preview.
I was able to open them in VLC player, but as we know, the codecs in that app are different.
I am not sure what changed that is preventing certain downloads to play, and others will not.

I am not able to replicate this with YouTube videos, however I can replicate this with several other sites that were supported prior.
It seems that the ones that do not work natively appear to be missing key elements.
I have tried to drop them into the Video converter, and it appears to 'convert' them, but they still do not open.
