mplayer started balkng at youtube - I thought maybe I was just looking at some slightly different filetype - so I followed some instructions somewhere, and now I get no SWF files read at all. Everything I try just makes it worse. If I tell firefox to use totem for flash I get GStreamer encountered a general supporting library error. If I tell it to use X11/gmplayer it says LAVF_header: av_open_input_stream() failed. I think my thrashing has dug me into a deep hole. I don't especially like chrome but it plays everything. Is there some step by step procedure for idiots that I can use to fix firefox? Thanks.
