Unusual high number of NSPlayer
 

Dear all,

I'm currently having an unusual high number of listeners wich UA NSPlayer XXX on my server. Around 35%. A "WMFSDK" is not attached to the useragents. Is there a known ripper software behind this?

Here are some NSPlayer Examples:

NSPlayer/8.0.0.3801
NSPlayer/12.0.7601.17514
NSPlayer/4.1.0.3856
NSPlayer/11.0.5721.5145

Thanks for your help!
