Rather "non-intuitively".. is you have to be on a (neutral) page when changing the Remote Code from the remote.
A (neutral) page is one in which the OK button is not currently being used for something else.
If your stuck on the "Clock Setup" page, or in one of the Menus, then your not on a (neutral) page.
The quick way to get the recorder to a (neutral) page is to hit the HDD then PLAY button on the front of the recorder to play anything, or probably be watching LIVE.
I've only done it from a "PLAYING" recording. So I can't be sure doing it from watching LIVE would work.
So once its playing the [OK] button is free to use, its not taken up by some other function in a Menu or Clock setting page.. so you can use it for setting the Remote Controller code.
So POWER ON hit HDD then PLAY on the front of the recorder, then press and HOLD the OK button in the center of the navigation cardinal of arrow buttons.. then press (or rather a firm tap is sufficient) the 1 2 or 3 Number button while holding the OK button down. There will be no indication that anything has changed, not on the front face plate of the recorder, not on the on screen display.
To test it, press the HOME button up topside and it should take you to the WHAMMY Page with the Big Icons starting with the TITLE LIST icon.
Use the arrow keys to "validate".
: several buttons like (HOME) will work no matter what the Remote Code is set to, the arrow keys only work when the Remote Code is correct. The on face plate display may display rc 1 (this is meaningless) it has nothing to do with the Remote Code currently set. If the "in setup menu" setting for "alert if receiving wrong remote code" is turned on, the on screen display will freak out and berate you about having the wrong remote code set in the remote.. but it will provide no useful information other than heckling you to do something. -- these all add up to Confusing and Worthless information.. its just better to know what the exact procedure "is" to perform blind and ignore the unhelpful information.
: I know I'm running like version 1.00 version of the firmware.. whenever it connects to the Internet Magnavox central asks if I want the latest firmware to be downloaded and applied.. I always say "no". Your able to get an rc 2 I have never seen that no matter what the Remote Code is set to.. so your mileage may vary. The Maganavox premium Apple store IOS App for wirelessly accessing the DVR is still available and for sale here in 7/2021 that may not last forever.. so if you've thought about downloading recordings with the app.. you might want to get the app before its gone.. or you can't buy the premium version anymore. VLC 2.2.4 see's its recordings as well... so there's that avenue to save to a transcoded mp4 file.
VLC can Play or fetch m2ts URL strings directly http://192.168.2.196:55247/dms/contents/FU_00010001_0000010300_SRO.m2ts
If you throw that into something like Firefox it will lite up Windows Media Player and start playing back the recordings.
OBS can pull the video in via the VLC Plugin from the same URL... rather non-intuitively, you have to set the VLC source to playback always, rather than only playback when it detects a feed.. it defaults to disabling the feed so nothing starts playing unless autodetect is turned off for the source. note: the VLC player doesn't have to be running to source the video through the VLC plugin, I just screen capped a snapshot of the VLC player to demonstrate it can browse the recordings list and pull the URL for each recording. All you need is the URL to configure the VLC PLugin in OBS.. its quite independent of the VLC player.
OBS has no trouble recording its sources to a file for playback later.. though its doing that in real time.. so its a slow process when offloading.
WonderFox can download the video at faster than real time speeds... and its a handy dandy transcoder with lots and lots of presets for doing everything from targeting a device for playback to determine the transcoded format, to ripping only the audio podcast style if you just want to listen to the audio on your phone during a drive.
