As above title says really. Using a LiteOn 40125S and a LiteOn Ltd-163 as reader for OTF audio burns. Had no problems whatsoever using V22.214.171.124, I've not tried the earlier beta versions of V4 for audio so I don't know if they were any different for me.
With CCD V3 I always burned at whatever speed took my fancy with "read subchannel audio" switched off. I have tried the audio and data settings for audio recording with V4 and it still takes a good 8-10 mins per disc with the Litey's red light constantly switching between red/orange.
I've been doing around 200 data discs a week with V4 on the Litey since the first beta was launched and not one single problem, in fact it's better than ever.
Olli any ideas if you are looking in?
