No, the old access cards are not compatible with the newer receivers. The DVRs (both the R15 and HR20) seem to have more issues with this then the the H20 and D11 regarding this. Using the previous series of cards will lead to constant lockups and random rebooting.kathymoore said:I have an old DirecTV access card from my deactivated HD receiver. It was used
for a few months last year, until I upgraded to the HD DVR. Is the old access
card still usable if I get another DVR or receiver?
