I am on my 3rd 3400. When ou 6-7 y.o box died they sent out a truck and the guy gave me a 3400, because I asked if he had one. (New is better tan old - right?).
Before I learned they were inheirently defective - called them in a few weeks and they shipped one out. Think they charged $10 - but could be wrong.
I soon learned the boxes all have defective software. I called and all they offered to do was send a truck and charge for a service call, OR, mail one! No charge and they included a shipping labrel for me to return the "old" one. (I am in Okld., Ca.) The previous time simply returned box to a nearby office.
As has been mentioned, you can't pick up at an office because they will only give you whatever (very) old box they happen to have. They won't give you a phone number so you can call a local office.
Most of the boxes that Comcast uses are 5-8 years old - a lifetime in the technology field. They have come out with model 3400 - but reports here and on indepent forums confirm they have major software problems. The problem is software - but they keep insisting on sending me yet a new 3400. On my 3rd one.
It is definitely software because at least one major company (can't recall, might be Time Warner) and when they updated the software - users said all was fine. The main problem is what is called the "Black Screen" problem. Sometimes all you get, when you click on the program that recorded is a black screen and can't FF or play it at all. Sometimes it will play for a few minutes before turning black.
BTW - Comcast will mail you a new deck. You don't have to go to their ofice. All you have to do is ask - they will not volunteer. Even if they charge $10, worth not having to deal with long lines in an office.
comcast has no idea on a daily basis what boxes they will have in stock, that changes daily based on installs and what stock the techs have. You cannot request a specific box from comcast. Like I said all you would be doing is getting more hard drive space. If that is your concern the go with the multi-room dvr that has a 500gb hard drive.
It would be nice if Comcast customer service could let me know what was available.All they say on the phone or chat they have no idea what would be shipped to me.They tell me to go to my service center which is 40 miles away to find out.Also the service center has no phone number.Maybe I should switch to Direct TV.
Are you in a cisco Scientific atlanta market or motorola? The main differences between all the boxes only is the hard drive size and weather there is an hdmi port. The motorola market also has a more updated guide.
