i think it has something to to with the whole vdr-machine. Some month ago i put my
sat-equipment in a new box.
AMD Athlon XP 2200 with 512MB Infineon-Ram on a ASUS Board A7N8X-Deluxe. In the old Box i got
the ring-buffer overflows not on plain vdr, but when i watch a DD-Movie and vdr (with
ac3overdvb-patch) was in Transfer-Mode.
