I ca oly conclude that there is something in the method Byker is using
when it comes to posting his image and video files with MS Windows Live
Mail, which is not a dedicted Usenet client.

When I download bykers video binaries using Forte Agent, the file names do not contain the comma after the
file extension and they play normally. When I download his still image files, they are displayed in a fashion
identical to Testagrose's postings.

The difference between the two is; byker is posting using base64 encoding and Testagrose is using uuencode.
