The problem here is they put this timeshifting layer right in the pvr plugin insted of having it as a seperate plugin available for ALL incomming streams. It would be wonderful to timeshift any stream comming from stdin, a fifo, a url, etc.
Do the xine people know about this design problem? You are right,
instead of adding timeshift to input_dvb.c, it should be added as
extra layer.
James Courtier-Dutton touches on this here:

I have seen the occaisional request similar to mine on their mailing lists as well. I think they would be receptive to changes here but someone else may have to do the bulk of the work.
So what do we need from a player, e.g. xine?
o Read from fifo to bypass dvb://, pvr:// or whatever. We could also use dvb://, but I like to 'see' the stream before xine gets it to read EPG and other fun stuff.
Well for xine we wouldn't have to impliment the timeshift buffer in Freevo but instead:
xine_input_plugin -> xine_timeshift_plugin -> xine_internals -> xine_output_plugin
The xine_input_plugin part could take care of regular V4L, dvb://, pvr://, stdin, rtsp, http, etc. We could select from one of these input methods or use a pipe or fifo to a stdin type input plugin.
I think changing xine-lib would save us much hassle in Freevo.
BTW, as for seeing the DVB stream before another app gets it isn't (shouldn't be) a problem. I think an outside app or Freevo daemon plugin could attach a filter to the EIT PID getting any infos it needs for EPG, now/next. We can display this info using a player's OSD interface.
