Hello Paul, The bulk of the problems you had are usability issues with userland applications rather than issues with the drivers themselves. When it comes to Linux TV applications, the US is much worse off in terms of digital support than Europe and other parts of the world. Much of this is a result of the fact that so much of this country uses cable rather than terrestrial broadcasting, combined with the significantly worse situation with regards to the DRM found in US digital cable systems which effectively prevents people from accessing digital cable on a PC. I can count the list of developers on one hand who work on US based ATSC and QAM drivers. Even fewer actively contribute to application support for these standards. The documentation is lousy, and those who go through the trouble to figure out how to get their stuff to work do not contribute back the information into the wiki. There are just too many devices out there, too many applications out there, and two few developers willing to dedicate the time and energy to do the work. The fact that there is also no way for developers to even recover their costs just further discourages doing new work (a challenge I've had given I've now spent hundreds of dollars on devices and tools and that money is long gone)... I'll get off my soapbox now. :-) Devin -- Devin J.
