I think part of the problem you will run into is that as analog TV
continues to get less popular, the cost associated with having an
onboard encoder will result in more and more boards not having them.
Compounded by the fact that PCs are continuing to get faster, it just
makes less sense to incur the cost (especially since many users cannot
tell the difference).

It's similar to the "Winmodems" of the late 1990's.  In the beginning
they were seen as crappy and inferior to regular modems that had an
onboard DSP, but over time the benefits of cheaper hardware combined
with computers becoming fast enough to do the work entirely in
software, modems that weren't software based became the "premium"
exception as opposed to the rule.
