It’s a pity that none of the US models mention anything about whether they have a mono or stereo tuner. Here in Europe, it is quite straight forward to see if VCRs or DVD recorders have a Stereo tuner, since if it does not say ‘Nicam’ anywhere in the manual, box or specifications, it has a mono tuner. However, interestingly while my LVW-5045 doesn’t mention ‘Nicam’, it does mention “Stereo/Main/SAP/Mono” for the tuner specification in the manual. I can confirm that my LVW-5045 has a Nicam stereo tuner, for example when I see a vehicle fly by the screen, the sound goes from one speaker to the other; following the action.
I downloaded the US LVW-5045 manual and the section about Stereo, SAP, Main and Mono sound selection has been cut out, which means it looks like if you haven’t found any manual mentioning about the audio selection, then it looks like LiteOn don’t make stereo DVD recorders for the US market.
The following is the audio selection on my LiteOn LVW-5045 (European model):
