We have had this discussion in another thread and yes you do have to record on a 256 from the inner portal with a multiroom sub and in my opinion the 256 is superior to the other mag boxes because I know from personal experience that it is faster at channel changing and going through the tv guide and the main thing is that it plays the newer codecs that the 254/250 can't and never will be able to more and more suppliers are starting to use for VOD and for the problems to be ironed out that you mention if you could give some indication of what problems you are having then maybe I could be of some assistance or are the problems you refer to that you just can not record through the stalker portal, the link you posted is just 1 person asking the question on the infomir site as I myself don't see any problems on my box that need to be ironed out, and don' take this the wrong way as I genuinely have no way of telling but do you just use techkings for your information as when it comes to iptv there are far more informative sites on the internet and if you are using a decent supplier they will have their own user forums for any problems you are facing. There could be numerous factors why you cant record like do you have multiroom, may be some settings are not correct on the box, have you checked you have a genuine box not a clone have you tried different usb's are just a few and the reason I had to post about your comments is that personally to me they have started to sound like rants rather than giving people interested in mag boxes genuine good advice and letting them make an informed decision like telling them a smart tv app can do the same thing. I personally use a smart tv app on LG 4k smart tv, Nvidia Shield tv using perfect player and dedicated app from supplier, mag 254 and mag 256 and for ease of use, ease of set up,family friendly device and full features personally I think the mag 256 is by far the best device.
