I bought an eSATA external drive when they first became available and I get a huge amount of storage space (something like 120 hours of HD).
Can you mix and match your old DVR with the new Quantum DVR? In other words, could I keep my old one up in the bedroom or is quantum all or nothing?
The 6 channels at once thing is appealing - particularly during football season ... but going backwards on recording capacity is a dealkiller, regrettably.
