There are several posts in the Navigatr thread on this topic, but it only appears to affect a few people. One I found was also for an LG TV, like yours which is a 768P TV (1366 x 768), but accepts 720P or 1080i (almost all TVs accept 1080i).
Make sure your TV firmware is up to date and check out the previous links to see if there is anything that helps there.
If nothing works, then you may wish to switch to component video/analogue audio cables to the TV.

I have checked for firmware updates for my set but there are none to be had. It maxes out at 1080i and nothing is going to change that.
The firmware in your TV should be telling the Rogers box the maximum resolution that it can receive, like all other TVs that don't accept 1080P. There is something wrong regarding the handshake with your particular TV (and perhaps other older LG models).
Whenever there is a firmware update there are occasional incompatibilities that arise, similar to when you update the OS on a computer and need to update certain older software.
Component video signals should not be considered "inferior" especially on a 768P TV, so you may wish to consider that route.
In order to avoid resetting via a "black screen", you could perhaps connect the box to the TV via composite video, switch the TV to that input and then change the settings, and then change back to the HDMI input. If you leave your PVR "on", you should only need to change output format after a reboot.
I know this is not what you want to hear, but it's a fact of life that older equipment sometimes becomes obsolete or requires a "workaround. Your TV is over 10 years old. You may wish to contact LG to see if they have a firmware update that your TV is not picking up. When I went to the following website a "chat" pop-up appeared - you could give that a try.
I agree that Rogers should have implemented an option for a "fixed" output option in the settings, instead of only providing an "auto-handshake" option each time you turn on the PVR.
Most other equipment (like BD players) have an option to either "auto-select" the output format or have an override setting where you can choose say 1080i.
Unfortunately the Rogers firmware is being utilized on STBs that have very limited memory capacity and each line of code slows down these boxes. The 8642 PVR for example is almost uselessly slow after the Navigatr update. That's probably why many previous options (like manual recordings, etc) have been removed from the firmware.
I believe another reason Rogers went this route is because there were quite a few issues for many customers with the 4K STBs (which also use Navigatr), not "remembering" their 4K settings. By utilizing the auto-handshake, this "forced" the 4K STBs into the appropriate format for 4K TVs.
Let us know what you decide to do. I certainly understand your frustration and hope I have been of some assistance, if only by explaining how some of these things come to be.

1. Did you remove the HDMI cable and any other cables you have between the 9865 and the TV?
2. Did you select 1080i in the settings before turning the 9865 off for a minute and then back on?
3. Did you do a reboot?
4. With component video connection (and no other video connections) the 9865 should "remember" whatever format you selected the last time the 9865 was on and it should not change to 1080p. You need to manually select 1080i. You may need to temporarily utilize a composite video cable to change the setting to 1080i if you just have a black screen. (yellow port - any RCA connector will work - like one of the component video cables)
Yes, analogue audio may not be as good as digital. To maximize the analogue audio, go into Settings - Audio:
Audio Range - Narrow (best for TVs) I assume you're not using an AVR (Audio Video Receiver). If you are, you could connect optical cable for better audio and use the normal setting.
Volume Control - Fixed. This will send the maximum audio level (best S/N ratio) to the TV and you'll control the volume with the TV, not the 9865.
As far as video quality is concerned, each input on the TV should be properly optimized. If done, you should have component video images that come very close to HDMI. Try various picture modes for example.
The Zoom mode on the 9865 is extremely poor. You should be using the TV's stretch/zoom modes instead. Just remember to "un-zoom" for HD. I never use zoom or stretch because the picture quality becomes poor and I usually watch HD channels. There is only 1 SD programme I watch occasionally and I leave it as is.
Good luck with Rogers.

2. No matter how many times I set the res on the Nextbox 3 it automatically changes to 1080P since the upgrade.
3. I have a feeling this is leading to my pixelation and screen freezing issues , due to higher scan rates processed, and some form of lower signal strength to my box.
4. i am assuming if I can lock at lower resolution, it will require less overhead for the box.
1. What is the exact model number of your TV?
2. This is because, even if the TV only displays at 768P (there are no current 720P displays, they are 768 x 1366 or similar), it does seem to accept 1080P if you're not getting a "no signal" issue with the TV.
3. Pixellation and screen freezes are almost always due to poor signal strength, at your home or in your neighbourhood. Call Rogers and have them check the signal at the box and in your neighbourhood. They can do this remotely.
4. I doubt this is the issue, as mentioned above.

You do not need to use the composite (yellow) inferior cable. The reason that the component video cables are not working is because your PVR is still set to 1080P, which cannot be output by CV cables on this box.
What you need to do is.
1. Disconnect HDMI cable
2. Using composite cable set the output to 1080i.
3. Switch to component video input on the TV and all should be fine.
4. Remove composite cable.
If the above doesn't work, here's an alternate method.
1. Using the HDMI connection, switch the output to 1080i.
2. Do NOT turn off the PVR.
3. Switch the TV to the component video cable input and it should work.
4. Remove HDMI cable.
Do not utilize the HDMI cable, otherwise the next time you turn the PVR on, it will go back to 1080P
I'm kind of surprised that the 4K box is a "solution". I would have thought that the Navigatr firmware is similar to/identical to, the firmware used on the 9865/8642. I would have thought that it also "shakes hands" with the TV each time it powers up and would utilize 1080P if it gets that "handshake" back from the TV.
