Tony’s got it right...blue ray is more demanding than simple redbook player is...was told more accurate?
All i can say is i have had the 105d for some months now and it is a pretty capable player...every audio place i talked to..."to shake this thing down" recommended it to me...even if I wasn't using it for dvd...
It replaced a considerably more expensive player and was’nt wanting to go that route ever again...so I had my doubts about this thing...
Does it have more s#*t than ill ever use...yes...its nice to know i have though if needed....no remorse here.
