This member function is called during the connection process.

It calls CBasePin::TryMediaTypes on both the owning pin and the pin connected to the owning pin, and it enumerates the preferred data type on the pin.

If a preferred data type is found, TryMediaTypes tries the media type with the pin in a call to the CBasePin::ReceiveConnection member function.

If this pin proposes a media type, its support is verified by calling CBasePin::CheckMediaType.

The enumerator can list all media types, even if some are not currently available.

This member function is protected.
