As BIGSAPOTEER mentioned above.
Tears of the Sun <---- best Blu-ray movie using the SL 25GB/MPEG-2 combo.
I think it's still the best SL25/MPEG-2 movie, correct? (inform me if this is not true anymore).
That movie alone shows you that you can produce superb image quality (and I mean D-VHS level of quality) despite the contrainsts of using bandwith-hungry MPEG-2 and the lower-end SL 25GB.
Despite these limitations, many people raved about it from HidefDigest and even on AVS forums for its quality on a basic-end package (Single layer 25GB/MPEG-2).
That alone says it all
