About PCI Bus (2.1,2.2,2.3...)

Hello there 8), i just joined the community but i've been reading you for a couple of weeks

I'm posting here because i've been searching around and couldn't find a solution to my problem.
I own a DFI Lanparty UT nF3 250 GB and i think it has PCI 2.1 (users manual talks about PCI Slot.. doesn't specify anything else) and i just found out that many TV cards require PCI 2.2 or 2.3...
I googled a bit and discovered that PCI 2.1 can work at 5v (but some sites say that they work between 3.3 and 5), then that the 2.2 work between 3.3 and 5 and finally the 2.3 that work only at 3.3v

Questions now:
PCI 2.3 based card could work and my board? (2.1)
My guess is that it should work if google is right, telling me that my bus supplies between 3.3 and 5. If so...
What's the difference between 2.1 and 2.2?

What i have clear is that if you PCI has 2.3 PCI slots then u wont be able use PCI 2.1 based cards as they need 5v to work and your PCI would only supply 3.3... doubts are between "old" boards with 2.1/2.2 using 2.3 designed cards...

Well hope you understood me!
Thanks in advance.

Thanks for the reply 8)
I've read so many problems with Pinacle tv tuners used on ASUS board (all of them were A8N Deluxe with 2.2 PCI slots)

May i ask if you use any TV Tuner? Which model?
