My laptop appears to have the ability of PCM & Dolby for audio.
PowerDVD Ultra appears to decode the Dolby Digital Surround EX 5.1 *AND* LPCM 5.1 just fine.
Yes, It does have HDMI as well.
EDIT: Just looked over my BDs, none seem to have DTS MA on them, but PowerDVD Ultra - well... pretty sure it covers all the bases.
