I flashed build 26 on my Quad plus and was having problems watching one program and streaming another via openwebif or the remotestreamconvertor to my 800ue+.
I rebooted the box several times but I just couldn't get it to work at all. I never tested recording but I would assume it would have been the same if I tested it.
Transcoding wouldn't work at all either just locked the box up.
Was the bootloader flash mandatory to use the new 2.3 based images? I never flashed the bootloader I just went back to build 24 and used the 31/7/14 drivers from the openmips website and the box is performing perfectly. All tuners can stream externally and transcoding works albeit with poor quality.
I never mentioned it as I just assumed that gigablue had made an arse of the drivers for the new kernel (like they normally do with major releases) and in time they would sort it.
