it doesn't, but the channel mapper i'm writing will. i ended up writing a parser to convert the json guide data that the DVR outputs into XMLTV, but ended up not needing it thanks to the awesome feature the devs added in which gives us the ability to map channel to guide in the playlist itself. i already had the code written though when i figured that out, so i figured i might as well just leave it there in case someone else needs / wants to use it.
i should have it ready at some point this week, perhaps as soon as tonight.
