It works quite smoothly for me with the same CPU as your (b), so I suspect it's due more to the outdated VDR or (more likely) DirectFB than CPU power. VDR 1.2 may be worth supporting until 1.3 becomes 1.4 stable release, but I think you should try upgrading from DirectFB 0.9.20 to .21 before worrying. I do have some issues though, I'm afraid: (a) A/V sync is a bit of a problem. It's probably mostly my fault for buying a sound card that cost only about �5 new and may therefore have a dodgy clock, but without any guarantee that a more expensive card would fix the problem I'd rather see a software workaround of dynamic resampling. I'm willing to do most of the work on this myself, but I think I might need lots of help from you, explaining the stages the sound goes through as it's decoded and buffered etc. (b) Sometimes when starting VDR after using MPlayer I get the blank white screen problem again and I can't make it work properly until I reboot. (c) I can't use VDR's mplayer plugin for two reasons. One is that softdevice appears to be leaving the sound card tied up, so mplayer can't play sound. The other is that when returning to VDR it either plays a couple of seconds of sound with a black screen, then locks up with lots of ringbuffer errors in the log, or produces a garbled screen in garish colours with only room for about half the OSD. When I used to use th DXR3 plugin, starting the mplayer plugin would pop up a message about releasing DXR3 devices, so I guess something similar is needed for softdevice to make it fully shut down and reinitialise. -- TH * http://www.realh.co.uk
