Hi Ted,

Please pardon my ignorance here..

On http://forum.koolu.org/viewtopic.php?t=5 it says "It is recommended
that the backend supply mpeg4 video.", I don't know what format the
video you get from the PVR-150 is, but is it mpeg4? If not, have you
tried transcoding to mpeg4 and seeing how it handles?
