Virtual media device network communication is improved with a media filter that reduces unnecessary non-media access commands, such as test unit ready commands, that have an enhanced impact on data transfer rates when media devices communicate over a network. The media filter withholds communication of selected non-media information by a remote access controller associated with a virtual media device and generates simulated responses to the withheld communication for return to the virtual media device. In one embodiment, predetermined non-media access commands are withheld from communication to a network unless a timeout timer is expired. The timeout timer is set for a time period that precludes a media change between timeout timer expirations and is reset with successful response to a command through the network.
