[linuxtv-softmpeg] problems with libsoftmpeg

[Juha Pahkala <juhis@trinity.is-a-geek.com>]

Hello,

Sorry to hear the development of libsoftmpeg is slowing down, it's such
an interesting project. I'm trying to get it to work but I'm having some
difficulties, hope some of you guys could help me out a little bit. 

I'm using directfb, fusionsound and libsoftmpeg from yesterday. My gfx
card is a Matrox G400. When I try to use the dfb_ts demoprogram I get a
very jerky picture for some reason, don't know why. 

One strange thing is, that the dfb_ts program says that my framebuffer
refresh rate is 52Hz, when it infact is 50 according to fbset program, I
don't know if this could be related.

bash:# fbset

mode "720x576-50"
    # D: 30.274 MHz, H: 37.701 kHz, V: 50.001 Hz
    geometry 720 576 736 576 32
    timings 33032 30 5 110 55 48 13
    vsync high
    bcast true
    accel true
    rgba 8/16,8/8,8/0,8/24
endmode

Here's what I get on the console when trying to use dfb_ts, i'd be very
greatful for any help I could get
