It’s time to face facts, minidlna and XBMC won’t run at the same time in Raspbmc. The basic UPNP included in Raspbmc won’t work consistently and Raspmc and is not nearly as stable as minidlna. OpenELEC is fast enough, but does not have the expandability of a full linux OS. I need to restart this project.
First thing’s first I’m going to straight up speed this thing up as much as I can. At the base level, this begins with the SD card. I’m going to go from a junk 4gb standard speed SD card to a 8gb SanDisk Ultra 30mb/s SDHC. On this I’m going to install the latest version of Raspian and overclock it to the maximum 1GHz.
I’ll keep you posted on how I progress.
Hey! This post was written a long time ago, but I'm leaving it up on the off-chance it may help someone. Proceed with caution. It may not be a good idea to blindly integrate this code or work into your project, but instead use it as a starting point.
