Shows not recording NOW....??????

I have only had the HR20 for a week and a half now and up until yesterday it was working good.

Last night we were not able to watch Medium, which we recorded and as Big Brother was recording, I went and tried to play it from the beginning so I could ff through the commercials and it went black screen and locked up. Had to hit the reset, which then lost my recording of the second half of the Big Brother.

I am so new to this receiver and this site, I am just curious what I should do, if anything.

Do I call Direct TV and ask for assistance?

Thanks
