The best way to check these files, is indeed the see in the first rar, what the file extensions are. At times i also do it that way, but it ends up with way more work, especially when you have several tv episodes in serie ( like on monday ) in your batch.
To many of those protected rar's are showing up these days. Even worse is the fact that they take over the identical filename, and poster name. As a result, when you pick one of the last files uploaded, you end up with the "spam" rar file.
