I just got one of these and have been playing around with it for the past couple of hours, trying to do just this. I have it set-up to display 10 shows and 10 songs. Seems to be running pretty smooth. THE font is a little different from SHSs, but still looks good.
I don't have any web space to post this to, and its not really finished yet, but if ya PM me Ill send it to you to mess with and you can tell me what you think as well.
I did NOT write any of the code in this. I just morphed SHS's and another script together and then tweaked it for my own tv. I do not take any credit for this, as this should be given to the rightful authors.
(sorry, but I forgot who wrote the other script) Ill look into it again so you get due credit. Still not sure who the author is of this script, but THANKS

got it from this site

Also, dgage, have you tried just changing the color in the style.css under the "active" portion. I have mine highlighted in the same yellow the SHS does. Just replace the other color with #DAB615. Don't know if it will work for ya, but it did fo me.
It would be possible to display more shows, I can fit 11 on the screen using this size font, but to fit more you have to adjust both the font size and the height in the style.css file. Lowering the height (spacing) between the words makes it even more difficult to read, so it would have to be adjusted per user. Ill leave the default at ten (or 11).
I just tried using the Garamond font (Looks close to the font used on the home page) and it makes it a little hard to read the list of shows. Very doable if I cut the list back down to 8 or 9, but at 10 it begins to get a little tricky on te eyes. I am going to use this font, however, in the bottom panel which dsplays the show that is highlighted (its a lit redundant, but I need to make use of the screen realestate. Now, if only we could pull more info from the mpegs to be displayed there, like show description (not just title).... that would be very sweet.
