I am confused on rather I need to do hacks to my win2000 SP2 registry to get DD/DTS passthrough to my SBLive X-gamer card. I have PowerDvD XP 4.0 and ATI DVD Player 7.6 - so far - I have NOT experienced any of the chopiness that i have read about in ver. 7.6 - I do NOT have the full ATI MMC installed - I did a custom install and only installed the 7.6 DVD player. As I understand it PowerDVD xp 4.0 does not do DTS decoding - but - Am I correct that it should NOT matter since I only want to pass DD/DTS through and do the decoding at my receiver or does the DVD player still have to know or have the decoders avail just to do DD/DTS passthrough ? Do I need ZoomPlayer to do passthrough ?
