It seems that since L403 my 622 has decided to not record any premium channels like HBO HD, SHOW HD or STARZ HD. Every week since the Tudors and Sopranos began I have set the DVR to record new episodes and every day after the program guide is downloaded these recordings are wiped out. It seems like it only happens on the these three premium channels. I have done a soft reboot but that did not help. Any suggestions?
