TiVo Desktop software gained some noticeable improvements, the main one being the software's ability to group .tivo recordings on the PC by series when they are viewed on the DVR. Also .vob files are now treated the same as MPEG-2 files.
TiVo Plus now allows Flip camcorder videos to be played back on the DVR, and automatic transfers can be set to portable device conversion. Some MKV files can now be transferred to the DVR, and to quote the software's release notes, it also "may recognize additional video types based on other software installed on your system."
