Well, I was unable to find a front end that could do everything I want. I assume that's why there was zero input from the community. I did find a piece of software that I figure I could share.
Ultramon - This has worked good so far to get everything going. Makes managing multiple video signals pretty easy and smooth. There's a free version out there and a pay version if you are a business using it. Lots of settings and configuration options. Well worth a look if you are running multiple video outs.
For sound I'm using a device called a Windy6 by Infrasonic (Auzentech). I had a hell of a time getting this to work the way I wanted. For our setup we want a device to be cable of passing multiple input signals out to an amp that is daisy chained to 2 other amps. The Windy6 comes with a fair amount of software. This thing is really designed to be used with musical/midi/mic devices, but also has the ability to use audio from a PC (or Mac I believe). The drivers that come with it may work on a normal device, but didn't do squat for me with Win 7 Pro x64. Specifically I wanted to use the PC as the audio source and pass everything to the box via firewire. I had no luck getting this to work initially. I tried the manual which is a 25 page PDF that is a freaking joke and their support is non-existent. I still have a trouble ticket open with them from last week and not a single response or update. I never did find a toll free tech support line either.
I did find a firmware and driver upgrade on their website. To update the firmware they want you to use a 32bit OS. They also want you to use drivers previous to the 4.4 version. I took the box home and used one of my Win XP 32 bit boxes that had a firewire port. I used the 4.3 drivers off of the website and then performed the firmware upgraded. After the upgrade I loaded the 4.6 drivers (newest as of right now) and it seems to have worked. The control panel for the device got a major facelift and it appears that I am now able to send audio through the device via firewire. I'm going back to the site tomorrow and will hook it back up.
So if everything works (which it should now) we'll have all of the songs coming out of the PC into the device via firewire. We'll have a run from the cable box into the device, a permanent line for the DJ to tie into, and a line for a receiver to tie into.
For video I went with 3 XFX GT240's. I have a VGA line running to a 15" touch screen behind the bar, a line to a 19" LCD in the basement for troubleshooting and maintenance. I have an HDMI out to a 2x8 splitter that will show shadow dancing on 6 tv's with capacity for 2 more. I have another HDMI out to another 2x8 splitter for visualizations. Right now I think we're going to use g-force, but we may change that.
Each splitter has 2 inputs and 8 outputs. We will have a cable box running to each. We won't show TV in this part of the bar except during March madness when KU (yes I'm a Jayhawk) goes to the tournament. The downtown area is freaking nuts during this time and it would be silly not to be open for those games.
The only video hangup that I've had so far is the 15" touch screen. I'm trying to get it to be the only device to display a screen saver. It would be a good place to show drink specials behind the bar and help out with the general effect. I'm also working on a manual to help the staff out. This is a new place and they're still putting the staff together, so hopefully I can get this going early this week. Oh, for the touch I am using a 15" Planar (can't remember the model # now) that works fairly well.
I'll try to get some pics taken to show you guys what I've been working on. It's been a pretty fun project so far, even with the headaches.
I would never die for my beliefs because I might be wrong.
