I am on V2 and no probs with iPlayer although only had the box for 3 weeks.Got hold of a T3-R the other day and very impressed with the functionality so far. Very speedy interface and reliable recording. The only things that seem glitchy are the iPlayer and YouTube apps, even when ethernet connected. The box crashed whilst watching a YouTube video in 4K HDR earlier, and watching a UHD HLG version of Doctor Who on iPlayer, the image started to glitch, then went kind of slo-mo for a few seconds before freezing completely. The remote was unresponsive so I had to pull the plug to reboot.
This was after updating the firmware to 2.03 as per @Clem_Dye 's instructions. Does anyone else get this? I'll contact Manhattan support tomorrow and see if it's being addressed.
