Please tell me do you see logo while playing file in the Elecard Mpeg Player?
The current version of Elecard Mpeg Player activates filters only for itself.
If you want use Elecard Mpeg-2 Decoder in other programs and do not see the logo you should buy Elecard MPEG2 Decoder and Streaming PlugIn for WMP from the following link:
http://elecard.com/products/products-pc/consumer/mpeg2-decoder-plugin/ In this case all applications that use DirectShow filters will use activated Elecard Mpeg-2 Decoder, and it will not show logo.
