The Sony DVMC-DA1 is a media converter without a tape transport. discoverAVC expects video sources to identify as a VCR in response to a SUBUNIT INFO Function Control Protocol command. But the DVMC-DA1 doesn't implement the AV/C command set, so it doesn't respond to the SUBUNIT INFO request at all. As a result, dvgrab doesn't know the device is a video source, so it won't try to use it unless you explicitly point dvgrab at it by GUID.
discoverAVC already has one special case to recognize Motorola DCT set-top boxes. This change adds another special case to also recognize the DVMC-DA1. dvgrab will then use the DVMC-DA1 without requiring a --guid option.
Since discoverAVC will potentially discover a non-AV/C device, it also changes the status text from "Found AV/C device" to "Found video device".
