ei001h,
I too have had several 4K discs freeze up on my new 205. Oppo (Chris) says it is due to defective discs. I don’t know if I completely agree with that. I remember years ago I had a Sonic Frontiers transport that had problems playing discs. Another Chris (Johnson) said it was due to bad red book CD’s. Turns out the player had lots of problems reading discs.
