I'm in Cincinnati, OH and have Time Warner Cable. I got a brand new Cisco 8640HDC HD-DVR last week when I upgraded to HD because I bought a new Samsung 46" B750 HDTV. I was looking for one of the newer Samsung HD STB DVRs, but the Time Warner rep indicted that many customers had issues with the Samsungs and that Time Warner was no longer purchasing the newest Samsung model. The Ciscos are Time Warner's newest hardware.
It has the 320 GB hard drive. The space available seems to be OK even while recording the Olympics in HD, but I have been watching and then deleting the recording every evening. It's premature, but maybe replacing the internal drive with one of the bigger WD AV drives (or getting a large external eSATA drive) is an option worth exploring to increse recording capacity.
The unit feels a little sluggish to respond to the remote compared to the old Scientific Atlanta SD DVR, however the PQ seems quite good. And the buffer seems to function differently then what I was used to with the old DVR. That is, if I leave a channel tuned while watching something recorded, when I stop viewing the recoring, I'm unable to hit the back key on the live program beyond that time point, not the roughly hour or so which is what I remember the old SD DVR kept in it's buffer. Specifically, I've recorded the prime time Olympics coverage, started watching the recording program a little later to skip through commercials, with the live program on that same channel. But when I finish watching the recording I cannot back up the live program (local news on NBC) to the start of it's time period, it will only go back to the exact time I finished watching the recording.
Additionally, even though I have the box's output resolution set to 1080i, which the TV is compatible with (it's 1080p native resolution), every time I turn the TV and box on the TV reports the incoming signal as 720 x 480i (SD) until I change the unit's output resolution to something in addition to 1080i, at which point the TV reports the signal as 1080i incoming. Then I can change the resolution back to only 1080i. However, when I turn the TV and box off, the next time I turn them on again, the resolution as reported by the TV is 480i again. I will try setting the resolution to auto to see how that affects the resolution output.
Has anyone else observed this behavior, the buffer functionality (or lack of) and resolution switching? Or has someone found a work-around?
