@paul_chiu ----- Thank you for your feedback and I am sorry to hear that this issue is continuing. Can you please describe, in detail, the topology of your current setup with the newly integrated Netgear gigabit switch.
Also, I’d like you to run a very simple test. Could you please move some files that have been giving you an issue over to your core machine onto the internal hard drive and try to play them back? Are you getting the same results?
