[SOLVED] Problem playing High Rez File

The diff between the 3B+ and SIG CM3+ Ethernet implementation is that the SIG provides a dedicated bus for Ethernet controller while the 3B+ has a shared bus for Ethernet and USB controllers. Its same throughput rating of 330 mbps but you get all of it on the SIG while the 3B+ provides up to 330 depending on whether other USB devices are using bus bandwidth.
