Here's the latest.  The Nvidia update to v9 including the hotfix has issues
for sure that affect Leanfront. This is the first time I've seen
mythfrontend be better than Leanfront on the Shield TV.  My test case was a
morning news program with a text crawl at the bottom of the screen.  right
now on my Shield TV the text crawl is perfectly smooth with mythfrontend.
with Leanfront the crawl is continuous, but you can't really focus on the
words as easily as Mythfrontend. The crawl in Leanfront shows the text as
if it's not in the same resolution as it should be.  Kind of like micro
shakiness making the text a little blurry or out of focus slightly. So
usable, but no as good as it was.
