Following our review of the Neuros MPEG4 Recorder, we have learned that it is not compatible with PSP Firmware Version 2.7. Recorded shows need to be converted in order for playback on a Firmware 2.7 PSP.
The Neuros team is currently working on a firmware update for the device which should correct the problem, which will be available for free download. It is not clear wether Sony did this on purpose in order to prevent copyright infringement of digital content.
