I'm unable to get this DVR's TV Guide OnScreen (TVGO)electronic programing guide (EPG) to complete initial data download via analogue cable (Adelphia -- no cable converter box). I've given the DMR E500H four overnight attempts at initial EPG data download. All attempts were over 24 hours and one over 35 hours. As directed I had the unit in standby for all 24 hour periods. The clock sets automatically but no EPG data. Panasonic troubleshooters have so far been nearly useless except to confirm proper setup configuration and to escalate this problem to Gemstar/TVGO. Does anyone know if certain cable companies are able to scramble TVGO's EPG data to promote their own DVR's? Are there firmware issues with this particular unit that Panasonic hasn't told me about? Perhaps I need to wait more like 3 days to get the thing to work or perhaps this expensive unit is a lemon.
