@Meowmix : I believe we are in agreement. The iHDD on the CAV10455 is 1TB. It is also 1 TB on the 9865. The 120 hours shown on the hardware page for the 9865 is incorrect (link below). It can record as much HD as the 10455.
Here's the arithmetic:
Typical HD channel - 15 Mbps (can vary from roughly 12-18)
3600 seconds per hour.
60% improvement due to media shrink compression:
15 mbps / 8 * 3600 = 6.75 MB/hr = 148 hours on a 1TB HDD with no compression, which provides for 237 hours of recording with a 1.6 compression ratio as I mentioned earlier for media shrink. Close enough to 240 hours for my tastes (ignoring the 1024 factor and other minor errors due to estimates and rounding)
Before someone gets too critical of the numbers above, they are rough numbers because:
- The HD channel bitrate can vary from say 12-18 mbps
- The amount of compression can vary depending on the amount of action in the programme. For example a talking head news programme can be compressed much more by Media Shrink than an active action movie or sports programme.
- The iHDD actually has about 931 GB available for recording, even though it's a 1TB iHDD.
That is why the 240 hours is only a rough estimate.
If you go into the diagnostics you can see the information for Media Shrink and it doesn't occur on the initial recording - that's bit for bit of incoming information. Media Shrink occurs after the programme has been recorded when the PVR is not busy doing other things.
@WiseGuy1: The type of issue you mention is almost always related to a poor signal in your home or in your neighbourhood. There is no way you had that many "bad boxes". Call Rogers and have them check the signal in your home/neighbourhood - they can do this remotely.
Welcome to our Community!
I am terribly sorry to hear that your experience with us hasn't been up to your expectations. I would have to echo the previous poster however in saying 7 or 8 replacements of the Nextbox 3.0 does seem excessive. In my experience, that would indicate something else is going on here.
I would like to take a look at the history of this problem on your account and work toward a better resolution for you. Please PM us @CommunityHelps for further assistance. You can find instructions on how to PM us here.
