TWC second DVR

[picopir8]

If I got a second cable box (first is an SA8300 w/ DVR service) and if I wanted it to have a DVR, then would I have to pay a second DVR fee or would one fee cover the service on both boxes?

Their website is a little comfusing I'll be the first to admit that:
Each TWC box, no matter how many or what kind is $7.95/month rental and each and every HD DVR box charged a service fee is added, so it adds up to $15.90/month total with box, remote and HD DVR fee.  
For example, if I have 3 HD DVRs so everyone in the family gets to watch whenever, wherever on any of the HDTVs,  therefore my fee is $15.90/month x 3 = $47.70/month.
I know it sounds pricey, but when one of them went out, a quick call and I got a replacement and a signal check right away (to be sure)
Better for me than buying three of them and since other "sources" of paid HDTV subscription are asking for cash upfront lately (for "lease") and so on, three boxes would be still be cost-prohibitive.
