I had previously worked on a patch for mplayer that fixed the LiveTV buffer lengths (if you FF past liveTV end-of-buffer, it ends the show). However, I thought of a better approach (and thus never released the previous patch). I implimented, in XMBC, the ability to open files on a myth-backend. It seems to be working well, and would eliminate the need for Samba shares on the myth-backends :) This would greatly reduce the configuration problems (and simplify it). However, before I submit the patch to XBMC, I would like some aditional testing. If anyone is capable of building XBMC, and is interesting in testing this patch, please post here and I will send it to you. It includes a patch to XBMC CVS, and a new set of scripts that I hacked together.
Sorry, my browser crashed when submitting this thread, could it be deleted?
