It may be an issue with the storage-device's software (where you are recording to). Or it could be the player.
I used to play while recording with my old Mediagates. If I recorded to my windows server, I could not play until the recording was finished (and the file was closed). But if I recorded to my NAS (linux-based), then I could start playing as soon as I started recording (just a few seconds behind), and it would play fine, trailing the recording, until the recording stopped. If I fast-forward to the point where I caught up to the recording, playback would stop. But I never needed to do that, as the main purpose was to be able to pause or backup a few seconds.
It might also be related to the recording software - What attributes it used to create the file. Opening the file with "exclusive access" would bone you. I always both recorded and played over the network using SMB (three separate devices), so that might limit the attributes available to the recording and playing software.
