I have had the Netbox 3 for about a week now and am pleased with it.
The only problem so far is that I cannot set it to 1080p.
My TV can handle 1080p since two other devices use that.
I can set the Netbox to 1080i and it works fine. The picture is great quality just as it was with my previous PVRs.
However, when I try to set it to 1080p, it goes to 720p instead. I have tried several times to set it to 1080p without any success.
I have read that some people think the Netbox 3's image quality is not as good as the earlier PVRs. This would explain that, since you think you are in 1080p but are actually in 720p instead.
Personally, I'd rather have the box upconvert 720p sources directly to 1080p, as this is a much easier conversion than having to interlace frames and therefore more likely to be higher quality.
It's debatable if having the NB upconvert to 1080p is worthwhile. If your display is 1080p, it's doing it anyway and, typically, displays do a better job than cable boxes. Assuming that it even works, where I could see setting the NB to 1080p would be if Rogers broadcasts 1080p content. Setting it to 1080p would pass it to your display as is, so no deinterlacing/upconversion would be required by either device. So far, no one is aware of Rogers broadcasting 1080p for anything.
I just turned on my TV this morning and the signal was 720p.
Yesterday, It was set to 1080i.
Looks like the box was reset overnight.
When I looked at the Netbox 3 settings, they showed 1080p which of course makes the PVR output at 720p.
I changed the setting to 1080i and that is now what it is showing on my tv.
From now on I will check the PVR each morning to see how often it gets reset.
I seem to remember that the 8300HD PVR had a passthrough mode. I would then get the signal that the Networks were sending. It would vary from 480i, 720p, and 1080i.
Is that option still available?
I also had an 8300 and used pass through. As far as I know, on the NB 3, your only options are to pick an output resolution, which the box scales to. Out of the box, the default setting was 720p and I changed mine to 1080i, so any 720p content gets upconverted whether you like it or not. I never watch SD content, so it really doesn't bother me. Upconverting to 1080i is fine with me. I have also played with the 1080p setting and I actually get 480p as mentioned by another poster above. To get the 1080p setting to take effect, you actually have to reboot the box. When it comes back up, even though the setting says 1080p, it's doing 480p.
Yeah, the lack of a passthrough option is what makes a functioning 1080p option important. Otherwise, I'd be happy to just let the AV receiver or TV do the upconversion.
For 720p sources, it doesn't make a lot of sense for the STB to upconvert and interlace frames to get 1080i, then go deinterlace and artificially recreate a full 60 fps. Seems to me it'd be much easier and better to go straight from 720p->1080p if you can.
Fortunately, most of the Rogers channels are 1080i AFAIK, which means this won't be a huge issue. Just an annoying one for people like me.
Even about 1+ years back, majority was 720 i think.. but as you said, MOST is 1080i now.
I would GUESS part of it was.. is that there was sometimes a BUG in the older software... wasnt SUPER common, but did effect some.
I know i got it a number of times, on my 1080p lcd i had at the time, with my 8300.
When it would switch between a 480i to 1080i channel on the box.. you would hear an audible click often as it did it.. and your TV would have to switch modes.
Now in current TVs, likely not as much an issue they are probably better built to handle it... but at that time, could often lock the TV up itself... have to turn it off and on.
