For me it was all about the DVB card or usb-dongle being ready. I never made it work (start from boot without a random long wait) but in a fit of frustration I installed mythbuntu. I can’t see what they have done but my myth aways starts from boot hot or cold start. Perhaps you should try to see what they have done and if it works for you.
