I have a Pioneer DVR and would like to hook it up to my TV where I have a Comcast Digital Set top box. Is there anyway possible to record onto the DVR through the Comcast Box so I can record a channel that needs to first go through the Comcast Box. If I bypass the Comcast Box then I will only be able to record up to channel 82. If there is a way please let me know. Thanks in advance for any help.
