It's been working OK. Just updated K-lite full and now VTM refuses most files. I must have altered something.
Log starts with [INFO] [2:00:57 AM] Program started
[DEBUG] [2:00:57 AM] .... Can't register codecs
Clearly something has changed. I can get thumbnails via Media Classic Player but not VTM.
Suddenly - Difficulty with many files
By now you should have mail with two sample vids and another mail with two runs of process explorer. The second email was copied to your second gmail address along with your regular address. The first one might have been marked as spam since it contained no message just the attachments.
