Hi all just bought a dvr-531h-s and was wondering a few things....

1. Has anyone tried to upgrade the hardrive in there unit?

2. If yes to the above question did it work? And if so what were the steps to doing it?

3. My EPG isn't on the front display anymore but when I go to the tvguide program it says there are no listings. Any ideas?

with the above question I did a unit reset because the channels were not showing up right and the EPG had been on for 4 days with only listing for 2 days.

Thanks for all the help
