I'm not speaking of creating a playlist that is accessible from the TiVo, rather I want to have it play whatever is coming being pushed through the soundcard.
I have DJ software on my computer and would like to use that since I can crossfade, add effects, etc.
I remember a year or so ago, I found a way to connect the TiVo by creating a bogus radio station that actually used the IP address from the PC. However, back then, it rarely connected and when it did, would often drop the connection. Also, there was a 5+ second delay, making any sort of mixing impossible.
