Only SVN trunk's version of MythWeb uses UPnP.  Also, the trunk version
does /not/ use the thumbnails created by the backend, and, therefore,
does not re-create the backend (recordings directory) thumbnails when
you go the the Recorded Programs page in MythWeb.

Based on your description, it sounds like you are using SVN trunk.  But,
remember that 0.20-fixes is also SVN, so just saying, "svn version"
means very little.  And, what I said in my other post was specifically
tailored to 0.20-fixes MythWeb, and Joe's suggestion--that your UPnP is
broken (bad router, bad firewall, or just the fact that Nigel is still
working on the UPnP/autodiscovery issues and may not be done with the
setup for machines using 127.0.0.1--it is, after, the unstable
development version) is far more likely to be the case on a trunk MythWeb.
