Making my own "channel", need advice/opinion/help
So I got a WDHDTVLive and a 1.5TB HDD last month. I love it, they're great! Holds lots of shit and plays everything so far. It also supports video playlists, so i been going through old discs and filling it with tv shows and movies. It can shuffle the playlist, so i kinda want to make a "channel" that is a playlist that randomly shuffles episodes, but I been thinking bout making some 'bumps' for each "channel".
For example, I can have a Shitbusters "channel" that just randomly plays crappy movies, and it might be nice to have a bunch of short (30 second or so) stuff in between. Just for fun, since probably only I would enjoy it anyway.
So I'm just asking for thoughts on this, and maybe some help or suggestions with art for a Shitbusters channel.
What i would really want is something that can play things at certain times, even will play it from the middle when i turn it on, just like tv, but i pick the lineup so its better.
