Answer : NO ... when both Byond and Byond PVR boxes function with same remote IR frequencies, hehe.

I am not sure but I think other alternative remotes such as the Logitech Harmony will not work because both Byond boxes use same IR frequencies.

Before I continue... the "Receiving Device (device)" I am now mentioning are the devices such as the Byond box, HDTV, DVD player, Bluray Player, Amplifiers and others.

Each device have a fixed set of IR frequency range that allows it to be controlled by its remote controller. For simplicity in explanation, I shall call it as IR frequency.

I will give you an actual true example. I have a Sony DVD player and a Sony Blu-ray player. Both these players have the same IR frequency. So what happened is that I can use the remote from Blu-ray player to control the DVD player and vice versa. Both the remote control transmit at the same IR frequency that both players will respond. So when I pressed the DVD remote "Eject/Open" button, both my players will eject the disc tray !!

What is needed is for the device to have internal settings that allow it to change the "fixed" IR frequency.

However, either one or both of the Byond boxes do not have settings to allow us to change its operating IR frequency.

Just for example only, if Byond 1 and Byond 2 are factory set at 8 to 9 KHz IR frequency range, 8.1 KHz for Volume+ so when I actually press the remote control Volume+ button, the 8.1 KHz IR frequency is sent out... and ... well... BOTH the Byond 1 and Byond 2 will increase the audio volume.

Let's say if I can change Byond 1 setting to use 10 to 11 IR frequency range and don't change anything to Byond 2. Now when I pressed the remote control, only Byond 2 will increase audio volume.

BUT both remotes are still transmitting at 8 to 9 KHz IR frequency range so I need another different remote which can transmit at 10 to 11 KHz range to control Byond 1 (with IR frequency settings changed).

Two things are needed here. One... the device must have the ability to allow IR freq setting change. Two... the 2 different remote must operate at 2 different IR frequency range or the same remote must have "switch" for different IR freq to be used.

Therefore, IF we can change Byond 1 IR setting, then I can use the Logitech Harmony remote to control it and use either 1 of the Byond remote to control Byond 2. A single Logitech Harmony remote can even control either Byond 1 or Byond 2 because this remote can set and assign different buttons change to which Byond to control. Not necessary to explain further on how to use the Logitech remote.

Once you understand what I have explained, you already knew that there is no IR (1, 2, 3) manual switch behind both Byond boxes... and the Byond software settings also don't have "IR Settings" to make any such changes.

So, for my Sony DVD and Blu-ray players, even if I use the original remotes or the Logitech Harmony remote commander, BOTH my players will still eject the disc tray when I pressed the "Eject/Open" button !! I must be allowed to change either one of my players or device IR settings BUT its not possible for both my Sony players. I had to move both players to further away from each other, hehehe.

Unfortunately, you cannot change the fixed IR setting for either one of your two Byond boxes.

My answer is still NO for your two Byond boxes. I hope you have understood my explanations clearly on the reason why.

NOTE: Probably Astro can set different IR frequency for Byond and Byond PVR, they did not... BUT I don't think anyone would have thought that people will put 2 Byond boxes near together at the SAME location... usually both in different rooms !! In most situations, Byond boxes are installed in different locations.

I admit that my knowledge in this area is not much and if any experts here find any mistakes or have any recommendations, please correct me or comment.. no problem, so that I will also learn too !

You are welcome.

Normally, it should not be a problem for you with 2 "boxes" (Byond PVR and "new" Byond) in different rooms since both remotes are not pointing directly to 2 "boxes".

You did not mention but I suspect that this is your current situation which you believe will have problems later...

1) You are presently subscribing to different Packages for your current 2 "boxes" (Byond PVR box and the old Astro DMT box).

2) There is a cable from the current old Astro DMT box in the living room to the Byond PVR room. And this cable is connected to a "device" with "Cats Eyes" that relay the IR signals from the Astro DMT room to the Byond PVR room.

3) From the Byond PVR room + another "device", you can use 2 remotes to change channels to watch channels subscribed for the Byond PVR and also for the old Astro DMT !

So, is this your actual current situation now ?

If it is... before upgrade... since 2 different IR frequencies are used for the 2 boxes (Byond PVR and the old Astro DMT), currently there is no problem to control the 2 "boxes" separately in the Byond PVR room.

Now, you worry that you will have problems to control which of the 2 "boxes" (Byond PVR and "device") in the Byond PVR room when you upgrade the old Astro DMT box in the living room... is this correct ?

Your problem can be solved if both "boxes" are subscribed to the same Packages so no need to control 2 "boxes" in the Byond PVR room.

I have a few questions for you here...

Question 1
Are the packages subcribed for both "boxes" different ? If different, what are the actual packages for the Byond PVR and for the old Astro DMT.

Question 2
Is your Byond PVR subscribed to more Packages than the old Astro DMT ? If more, then you can think of upgrading the old Astro DMT box to Byond for RM 50 per month during current promo to watch the same Packages as the Byond PVR.

Question 3
Is the old Astro DMT box actually the 1st Primary box and the Byond PVR the 2nd Secondary box ? Normally the old Astro DMT box started first many years ago before Byond was launched so this should be the FIRST box. Is the the Byond PVR currently at 50% special monthly subscription ?

Once the old Astro DMT box have been upgraded to Byond with same Packages as Byond PVR, then you don't need to use the "device (with IR relay)" in the Byond PVR room.

I am making a lot of guesses about your current actual situation. Without further explanation from you, I don't know whether my suggestion here apply to your situation, hehe. I may only be able to make a more accurate suggestion when I have more info.
