Those functions were used to transform the transport stream into
something resembling a program stream. If you just want to use the
video and audio devices and not the dvr device for playback of
transport streams, you don't need them. You could remove all code
concerning the dvr device.

By the way, about a year ago I was contacted by 
Avi Cohen Stuart <astuart at baan.nl> and he wanted to work on the margie
drivers. I gave him my latest sources and I think he got some of the
adaptations to newer kernels done. I haven't heard from him in a
while, so I don't know what became of the project.
