I may possibly be way off here, but can the neomagic hack be a useful (interim) model here? (from 'man neomagic') Option "OverlayMem" "integer" Reserve the given amount of memory (in bytes) for the XVideo overlay. On boards with limited memory, display of large XVideo buffers might fail due to insufficient available memory. Using this option solves the problem at the expense of reducing the memory available for other operations. For full-resolution DVDs, 829440 bytes (720x576x2) are necessary. Works for me. Dag B |

It only allowed you to use memory that was within the limits of the 2d engine. Alex |
