I posted on here a while ago asking for help with a lip sync issue I was experiencing on my toshiba sd530e DVD player. Subject: Lip sync issues with sd530E I have owned this player for around 3 months, whilst very happy with picture quality, I am experiencing problems with the audio. Specifically, when I play a DVD with a DTS soundtrack, after around 1/2 hour viewing I have lip sync issues. If I cycle through the available audio tracks back to DTS(without stopping the disc), the problem will be corrected for another 1/2 hour or so. Obviously this is not an ideal situation, as I prefer DTS soundtracks! Dolby Digital presents no such issues. So according to toshiba lip sync problems with a DTS soundtrack is normal Knew I should have got the 575.
