I have a Liteon LTD-163 as my current reader, and was wondering if the LTD-166S is a better reader. I want a reader that reads games, cd-audio, protected discs, and most if not all dvd formats (like I said…a reader that is good overall). If the newer LTD-166S is better, is it so much better that it’s worth the upgrade? I have had my LTD-163 for about 1.5 years now. All opinions are welcomed.
