For boxstar I was thinking of having the live buffer in RAM to save writing to the HD, and even wondered about having it in the player front-end instead of the server. Both approaches have their pros and cons. The beauty of virtual memory is that it works both ways. An application written to use a file can have the file cached in RAM and one written to use RAM can have it swapped to disc if the RAM is needed for something else. But I wonder, does writing to the HD really shorten its life significantly compared to constant spinning or frequently being spun up and down? -- TH * http://www.realh.co.uk _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
