10-bit vidcard and a 10-bit display? This switch in terminology recently is hella confusing: does a Geforce 330M outputting 1080p @ 32-bit colour via HDMI to a Samsung LCD FullHD TV meet these criteria?

No they do not, you need a professional graphics card and high quality monitor/TV.

I say we create more slots or at lease reserve one slot for 8-bit.
Here is my opinion on 10-bit vs 8-bit. 10-bit IS better than 8-bit. But is it worth it?
WARNING: the following content can be a little bit technical.
Here is some theoretical advantages of 10-bit (precisely speaking it is H.264/MPEG4-AVC Hi10P):
1.1. 30 bit per pixel (bpp). (This is the only advantage of 10-bit. The rest are H.264/MPEG4-AVC's)
1.2. Compression is 10bit by 10bit. Saves bandwidth.
1.3. Motion compensation can be performed on 4x4 blocks. whereas mpeg-2 16x16.(which means even if your monitor do not support 30bpp, you will still get a little better quality )
1.4. Support chroma sub-sampling 4:4:4 (with further extension to MPEG4-AVC) ,whereas MPEG-2 4:2:0
The disadvantages :
2.1. High CPU consumption
2.2. Most LCD support only 8bit per channel
A viable solution is to choose a 8-bit codec which support 1.2, 1.3, 1.4 (for example H.264/MPEG4-AVC HiP).

Well I suppose the party is over for this easy solution to watch high definition files from your computer wirelessly on your big screen. I think the argument is pretty much over about the decoders. I've prolonged moving my PC into the living room for too long and apparently spent a hundred dollars too much for the convenience of wanting to keep my office and living room separate. Buy another computer for living room? Not exactly in everyone's budget, but Pivos and other companies are working on creating new products that will play 10-bit encodes. How long until they hit the market? No idea but moving the computer to the living room and hooking it up directly to the big screen seems like one of the only options left for the high end convenience. If I have to I will, perhaps the ps3 or xbox360 route might also work. I voted to keep 8-bit around in the (A slot) but admit it is completely in my own self interest and not in the best interest of the bakabt staff or the direction of Bakabt in providing the highest quality video when possible. :o Do what you must, it might not be convenient for everyone, but sometimes the hard decisions have to be made. I do appreciate the open conversation on the issue though. Some very creative solutions to solving the problem have been mentioned in this forum. As for the argument over fansub groups not offering 8-bit encodes anymore this winter, I'm guessing people are still going to complain. But this fall I really didn't have any problems finding 8-bit encodes and was grateful. I suppose as long as there is still a demand, groups will continue to try to please until it truly becomes too much of a burden. Of course if were up to me, 8-bit and 10-bit high def encodes would become the new standard and 480p would be finally placed to rest accept for when it's the only known release available of course. ::)

Elaborate.
What if I say H.264 SD is silly?

Standard H.264 is different from H.264 with Hi10P extension.
