i have just one hi-res from HD Tracks 24/96 and it was fine.
Did you also tried to go back and forth from different high resolutions tracks ? ( from 24/88.2 to 24/196 to 16/44.1 to 24/44.1 etc...) Did the D-Premier follows easily the different files resolution ? Same experience in Dual-mono ?
Thx for any feed-back
Best Regards
