Could someone please bump the priority on this?
I've got a Panasonic P50V10E plasma which accepts Video levels (16-235) and I am running XBMC on my Linux HTPC. There is currently no way to get proper output so I'm forced to live with crushed blacks or whites. And I'm not alone, many more people have HDTVs that only accept video level input. Besides, nearly all HDTV content (blu-ray and cable/sat) are in this colorspace, so it would make sense to support this.
The windows driver has it, it shouldn't be very hard to include this in the linux driver I hope?
