Hacking a Samsung Direct TV Tivo DVR

JosephR's picture

I was given a Direct TV Samsung Tivo DVR model SIR 84040R.  IT has the card with it but I don't think it was a lifetime subscription.  Is there any way to get it to record over the air antenna TV?  I just want to use it like a VCR even if I have to manually start and stop it. 

I'm new to this site so I don't know if this has been covered before.  Any help would be appreciated.
