I guess transferring the recorded programs from Myth is a nobrainer as hey are in MPG format now.
Yes, they can be directly read with mplayer through a vdr's plugin, or be converted with nuvexport.
But I still don't know whether there is a tool to convert a mythtv recording to the native vdr format, for example :
/video/<Name of the recording>/2006-03-05.21.48.50.99.rec/ 001.vdr 002.vdr index.vdr info.vdr
Does somebody know how ?
