When I first got the recorder, it did actually hang quite a lot, however once I applied firmware 197-UK, I think it may have only hanged only once throughout the 4 week review. To me, the audio sounds fine directly from the Lite-On itself and I didn’t notice any unusual background hiss, unlike what most PC onboard soundcards pick up. I tried recording from various sources including CDs, over SCART, TV, etc. However, as the audio output (over Phono and SCART) is fairly high, it can cause distortion on audio equipment that has very sensitive inputs. For example on my PC’s sound card, I had to set the Line-in level fairly close to the bottom to avoid the input meter from peaking. I did also check for other issues that people mentioned in user reviews back in January such as audio-video sync problems after an hour of recording, remote keys acting if pressed twice, etc. However I haven’t encountered any issue with the remote and after a 2.5 hour recording, the audio & video was still in perfect sync that I could see, i.e. ‘B’ & ‘P’ sounds matched the person’s lips.
