PyMythTvFs
Fed up with MythTvFs breaking on my Linux MythTV backend when I upgraded MythTV I created PyMythTvFs.
PyMythTvFs is a Fuse based file system written in Python for accessing MythTv recordings as a file system. It's still very much work in progress but it is functional and allows playback of recorded programs.
In the future I intend to add several other features, such as folders, delete support and custom format strings. That's still to come, but for now it allows easy watching of MythTV programs.
