You know, whenever this topic comes up, I always wonder if someone could
take the time to create a Myth plugin that automatically sends an e-mail to
the network in question informing them that because of 5C DRM you just
aren't watching their program. It would be great to see the networks get
enourmous amounts of negative feedback about their DRM efforts.
I have not gone HD yet, but I absolutely dread when I do. I know from all
the postings on this list with problems, that it will be sheer hell to make
work, if it can be done at all. As for me I know that when I finally get
digital cable I will refuse to watch any show with 5C enabled (even live).
Maybe networks will figure out that making their shows virtually unwatchable
for a certail segment of their market is a really bad idea. I hope they
will, but I'm not holding my breath. I'm also not eagerly running headlong
into that wall, yet, but someday, I'll have to.
