Here in Columbia, SC, TWC charges for each DVR. When you order digital cable, one digital receiver is included in the price. If you want to upgrade that receiver to a DVR receiver, you have to pay an additional $5. If you want two DVRs (like I have) you pay a $5 upgrade for the first and $15 for the second (which is their normal $10 for an additional digital receiver plus an extra $5 for DVR service). So I pay $20/month to have 2 DVR boxes.
