I hadn't planned on submitting anything for release as this issue seems
pretty specific to my IPTV stream provider.
I was able to finally get things working with the following changes:

It seems that the request needed to define a user agent other than a web
browser before the redirect would happen as well as other modifications to
the header data. Once I implemented
setAttribute(QNetworkRequest::FollowRedirectsAttribute, true) it worked
swimmingly with the redirect.
This patch is pretty specific to someone using IPTVsubs as their provider
and I'm sure there is a more robust solution, but it works for me.
Thanks again Stephen for your suggestion regarding using wireshark to
monitor the network traffic. That was invaluable to determining the nature
of the problem.
