After fighting to get DVR recording to work, at this point am confident about making it always work. It really depends on your hardware. Whether it NVIDEA SHIELD, or Formuler, or Fire TV, or UGOOS, or ONN, etc.
Sure some will claim nonsense
RULES:
1). USE Wifi 5 or WIFI 6 always. If you use wifi. You need to send a video stream of data too your device, And back from your device. Any glitch in communication will crash the stream and stop a recording.
2). USE Ethernet if it’s available. It’s good to have something that can’t not be stopped or interfered with.
3). Most apps have the ability to record to a NETWORK ADDRESSES SERVER (NAS) using the SMB communication method. As with any pushing of stream data two ways, you need to make sure no stream breaks happen. Is that going to be better with wifi or Ethernet in your house? Can you set up a NAS on your router or a workstation on your network? It will take some effort to perfect this.
4). Would you rather record to a local USB memory stick? Well that’s a problem. The memory stick typically uses FAT32 with its file limit size. Sure you can use it for half hour or one hour shows, but then you run into issues at anything over an hour. It will be a fight with using that USB as they can random disconnect also, depending on hardware.
5). Using the five to ten pieces of DVR software to make this work, as you experiment, will not be fun. Then you have to consider if you are using ANDROID 9, or ANDROID 11, or ANDROID 14 or the android tv version, or the proprietary fire TV android. The software and operating systems can fight with each other. Will the software allow you to watch something and record something else, without crashing the streams?
6). Your provider of internet programs will cause issues too. Are they rock solid every day? Do they have outages? Is their EPG up to date for a day or a week? Do you get one stream or two streams?
7). Finally the hardware. Many say just buy an Nvidia Shield Pro for $200 and be done with most of these issues. It runs older version of Android, and Nvidia made sure it’s all up to date with the ability to use NTFS USB attached devices. It’s an old hardware device though, and many want to try new hardware, where each platform still depends on the manufacturer.
It’s a rabbit hole of information. Good luck with the hobby.
