I use a Minix U1. What do you guys used for cachemembuffersize in Minix XBMC ? Since I have 1.1 GB available RAM, I set cachemembuffersize to 350,224,438 bytes (334mb). For the other parameters, I set buffermode to 1 and readbufferfactor to 1.5. Occasionally, when I fast-forward, I would get the message "Source to slow. Read rate to slow for continue playback...". Is there any way to check how much RAM is used during video playback? When I press control-o, I can see Memory used is 41% and this value does not change. Is this the RAM used?
