Soon
- re-implement basic things with gstreamer (video size, crop, framerate, etc)
- store/load configuration from file
- let the user choose the muxer avi/mpeg/ogg
- video preview
- video source/tuner configuration

Later
- maybe replace in CodecConfig the codec list with a combobox
- possibly accept other video source ? (ieee1394, screen, etc)
- remote control interface ?

Internal
- check for gobject/gst unref (DVR::start, findcodecs, etc)
- rename TabCodecConfig to CodecConfig
