I'm going through Comcast. My S3 has cable cards and my SAS2 is just coaxial cable. They are both synced with comcast time. Every show I record has the last minute or two cut-off, it's really annoying. You might suggest I "add minutes" but that will clip my other shows. Besides why do I need to do this? It's supposed to work correctly in the first place no? Is this a common problem?
