Someone had recommended this too, http://libsyn.com/, but it's expensive also. I create one to two 1.5 hour sessions per week, each is about 75 MB, so 150 MB per week. The alternative is to just create a static video out of it (static picture background) and upload it to Youtube. I tried that and it makes the sizes twice as large, which is fine, except that then whoever has the link can access the audio (even if it's unlisted). This is the piece I'm trying to figure out (how to protect the file) and make it available in my XF forum for upgraded/paid members.
