The big issue with this board is not the tuner itself, but the PCI bridge. Developing the drivers for a bridge can take months of work, and unlike bridges from NXP or Conexant which are used in dozens of products, this bridge is only ever used in this one board by this one vendor. And in the cases of NXP and Conexant bridges, usually the person writing the driver for the bridge has real documentation. It just isn't worth any developer's effort to spend three months reverse engineering a bridge to an older and more obscure product with no supporting documentation (and three months as an estimate is what it would take an *experienced* LinuxTV developer who has worked on other bridges). There are just *much* better uses for developer resources. Also, not only is the bridge not supported, but neither is the demodulator (it's an ATI312). Again, no documentation and it's only used in that one hardware design, so it's not like the work would really help with other more popular products. Devin -- Devin J.
