My Sound devices 744T (currently running 2.66 firmware), appears to only have the option of 48.048kF mode in 30ND frame rate. Does anyone know if the hard disk recorder has the ability to record at 48.048Khz F-mode with true 24frame rate. I have heard that perhaps it can if I do the firmware update, but I read the update specs on the sound devices website, and frame rates/sample rates were not listed. I have a feeling the upgrade only applies to the 788T, but if anyone can shed some light, i'd appreciate it.
