Updated Cable Card? Issues

[Danno321]

I have the cable card from about two years ago in a Moxi DVR (bought by Arris, no longer available).  I have been experiencing channel change issues where I will be on the same same channel but the info and number are for the channel I was trying to tune.  I am also getting "you are not subscribed" message much more frequently.  Is there an updated Cable Card/SDV Box?  TIA
