On the Verizon web site they state that you can get 80 hours of SD TV and 20 hours of HD TV recorded using the HD DVR Media set top box. My experience is not the same as advertised. My set top box is getting 5 hours and status shows it is at 54% capacity which means it will get less than 10 hours recorded. My question is does this indicate my set top box is failing or is the capacity overrated by Verizon?
