I have been messing with modules/tv/includes/objects/Program.php and  
applied this patch
which appears to fix my preview image issue:

          // Figure out which host holds the recording
              $urlparts = parse_url($fileurl);
-            $host     = _or($urlparts['host'],  
$GLOBALS['Master_Host']);
+            // $host     = _or($urlparts['host'],  
$GLOBALS['Master_Host']);
+            $host     = $this->hostname;
              $port     = _or($urlparts['port'],  
$GLOBALS['Master_Port']);
          // Transfer the pixmap from the backend

I guess my question is, how is this supposed to work?  is mythweb  
supposed
to contact the backend that holds the recording directly or is it  
supposed to
contact the master backend who will then contact the slave backend?

The streaming/downloading stuff is still broken so  I know that
something is still missing.  i see 0 upnp activity on the slave  
backend during
all of this as well.  Does the slave backend also need to be running  
mythweb
for this to work properly.
