I use SanDisk Extreme PRO, I did some testing with Feb15 build and.. with sd_uhs module, I was able to record mv1080p 12bit lossless for more than 1min..., 14bit lossless I get only around 15s, but with sd_overclock script, I am able to record for more than 1min. With Mar24 build, I was able to record mv720p at 12bit loosless but nothing more, so it seems that sd_uhs is not working properly there, but when I copied sd_uhs module from Mar24 to Feb15 build I was able to record mv1080p 14bit lossless. Are those modules between Feb15 and Mar24 any different?
