Probably not. The time to question it was when the installer called to say they were on the way and if they didn't have a HR24 to reschedule. DIRECTV considers the HR21/22/23 all the same, a HD DVR, which is what they advertise, not a specific model, except for the HMC/HR34 which is a different beast.kash said:Just got a new install the other day, i got what looks to be a totally used receiver. Do you think if i call and get directv to switch it out i'll get a newer hr24? or will they send the same 23?
