The TBS cards use the same cx23885 device that the Hauppauge HVR 1250 & 1850 use, both of which support RC input. The problem, as I understand it, is that in some modes the cx23885 can produce an interrupt storm. Given that the current v4l RC architecture is unlikely to change significantly in the near future then instead of bleating, perhaps TBS should contribute a fix. However, given that to date all of TBS's code has been kept private then that's unlikely. So the TBS Linux drivers are likely to become increasingly incompatible with current Linux kernels. I have a need to use my 6981 card so I'm developing my own fix for the RC problem. I'll post this to linuxmedia when I'm happy it's sound. Incidentally, the latest TBS 6981 driver OOPS with linux 2.6.39 even though their release note says "Ensure compatibility with latest ArchLinux (with kernel 2.6.39.2-1)". This is due to a change in an i2c driver structure in 2.6.39 and is a direct consequence of TBS shipping object modules built with old kernel headers. Be warned, the h/w is sound but the software & support suck. -- Lawrence -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
