UPnP Devices doing multiple accesses per file

Many UPnP devices do not use a single HTTP request to get a file. Instead, they'll do several. Typically there's a couple of accesses to get the header bytes, another access for the first 64K bytes, and then a final access for the rest. For video, I think I've seen accessing the entire file a chunk at a time.

If the file takes a long time to set up (such as a file that requires converting on the fly), this may cause pauses in playback.
