...as supplied byTime-Warner. Unfortunately I don't have any experience with the ones you mention. Generally speaking, I've been very pleased with it for recording and "time-shifting" programs. I am also able to record 2 programs at once. Because the DVR is built into the cable box it utilizes the built-in program guide (i.e. Time-Warner) for recording programs - this is a huge advantage and I'm not quite sure how the other brand DVR's would accomplish this - I know that Tivo uses a dedicated phone line to download progam data.

The only disadvantages I've had with it are 1) It's noisy - I can hear the hard drive from my lazy boy... and 2) there will occassionally be a pause while watching normal tv (this thing is recording ALL of the time) and during playback of recorded material. Channel changing seems a bit slower too. The pause isn't a big deal, but I wish it were quieter.

I sure wouldn't want to go back to VCR recording - this thing is SO convenient. No punching in channel #'s, start and stop times, or tape speeds. Simply use the program guide and hit the REC button on the remote - then it prompts to record a single show or the entire series. Sweet. Playback involves hitting a LIST button and choosing the recorded show I want to watch.

I hope this helps. Good Luck.
