Hi. I've pretty much finished my little project -- I'm still waiting for the rgb-vga cable. Since I?ve been away from this thread, I?ll put all my responses here instead of to the individual posts.
MiSfit, I think I should be good with the rgb-vga cable because (I think I didn?t mention) I?m using a projector that came with an rgb-vga connector. So basically, I have 3 rca cables snaking from the back of my projector (mounted on the ceiling) to a regular rca switch box?s input. I then have sets of 3 rca cables from the switchbox to my digital cable box, my dvd player, and soon to my PC. Since my PC only has vga out, I ordered the rgb-vga cable for it.
My digital cable box and dvd player have rca outs for digital sound so one rca cable for each also goes to the switchbox. I just push the proper button on the switchbox if I wanted to watch cable or dvd.
For the meantime, since my PC?s rgb-vga cable is in the mail, I connected the GX260 directly to the projector using a regular vga cable, sans any vga-rgb adapter cable.
Soundmanred / ViRGE, I found in my box of old spare parts a Turtle Beach Santa Cruz soundcard. It?s supposed to send 5.1 signal through its 3.5mm ?Versajack? output. And since I discovered that the GX260 actually has two full-height horizontal PCI slots, I tried it first. I didn?t have to buy the low-profile Audigy SE.
However, I couldn?t get the Santa Cruz to output 5.1 sound. It only outputted 4.1 sound. The center channel -- and thus the dialogue in movies -- stayed silent. Then I remembered I have an Audigy MP3 soundcard in another PC whose motherboard already has onboard sound. Since I only use that PC for working-at-home via VPN and not for watching movies, I took out the Audigy MP3 soundcard and used that instead of the Turtle Beach Santa Cruz. It worked great! I only needed to buy a 3.5mm-to-rca adapter at RadioShack to connect it to my switchbox. I now have a 5.1 ?media center PC? built out of junk parts
.
I also installed a wi-fi card I ordered from 3btech ($13 PCI card instead of a $15+ ethernet cable) so I'm watching Netflix on it, too. I only wish Netflix would stream 5.1 sound and not just stereo.
I'm excited that I now wish I can also play games on my projector. I wonder what games the low-profile AGP boards at Newegg for under $40 could handle. Far Cry? NBA Live? Would be nice if they can handle a 5.1 PC game...
