I just moved my DVR drive from a 5400 rpm 2 Tbyte to a 123 Gbyte SanDisk. The video performance improved 2000 %. No more pixelation and smearing of big blocks of color. However the lip syncing is off by roughly 1 second. Can You explain why the video improvement? Can you suggest how to fix the lip syncing?
