Its certainly curious to be synced at EXACTLY 60/20, that's not a profile rate AFAIK. Even DLM banding usually would do something like 59998.
It's DLM banding as mentioned in his other thread.
60Mb banding can be at 59,996, 59,997, 59,998, 59,999 be or 60,000.
While it's more common to be just under an exact figure, many chipset versions do show a nice rounded sync number.
