It was very good to read your post, because I thought that I was the only one that was trying to do this I-opener DJ thing. I'm at college and DJ parties.
Here is my setup: Technics 1200 turntable, numark 1001x mixer and an iopener:
Here is what I did to the i-opener to get it to play MP3's into my mixer:
1) bought a lasagna fan - you have to do this.
2) bought the i-mod 3 kit from codeman - you also have to do this to get the laptop HD to talk to the i-opener
3) bought a laptop hd, 6 gig - good enough for some MP3's
5) bought a linksys ethernet adapter
6) just ordered a USB to 1/8" audio adapter from crutchfield.com - this should just plug strait into the back of my i-op's usb port and then I can run a male 1/8" to RCA connecter (radio shack!) into my second channel of my mixer. This should work.
7) 128 mb of ram
Here is what I have discovered while trying to get MP3's to play well on i-opener.
1) my mp3's would skip, about every 5 seconds, even though I had 128 mb of ram. I thought it was a disk thing, because whenever it would skip the disk light would come on as if there was activity. I went through and tried the suggestions of the IDE channel stuff, but what fixed it for me was VERY simple. I just disabled virtual memory. Now it rarely skips and I can run ie, winamp and aim all at the same time.
Now to the hard part. I am using the stock 266mHz processor and NO level 2 cache. There is no prebuffereing either, so mp3's take awhile to load (2 secs). For cueueing and such this is unacceptable. So winamp is out of the question for now, because I need precision. I dont know if a program like virtual turntables will run well, because it not only does real time MP3 decoding, but other things as well (pitch changing, cueueing etc).
When I've got something playing on I-Opener I can cueue with turntable no problem, but going the other way is hard. Most of the stuff I do is precision scratching, so what I think i'm going to do is loop beats on the can-opener and then scratch over that with turntable.
I am running win98 because I had a fit trying to get rh linux installed, and win98 requires less of a footprint than win2k. Also, win98 has nice drivers.
Are there any other i-op dj's out there?
I just think it would be so cool to have 100 people dancing with me behind a dj table scratching on a turntable with the blue light of the i-opener lighting my face. yeah!
