SA8000HD-DVR Recorded Programs Disappear

[msofan]

I've had my SA8000HD for a while and I've noticed that shows that were a while back no longer show up under the "LIST." I used the diagnostics to show the remaining room in the hard drive and it said there was plenty of room!  :confused:  Are shows automatically deleted after a certain length of time? Is there any way to retrieve the shows that were "automatically deleted.?" I now indicate "Save until Manually Deleted." Was not aware of that until recently. BTW - what is the best way to save SD to a PC. Are the PCI cards from Hauppague reliable? What about the USB2 options? I don't really need the built-in TV, just a way to get good, clean video and audio output so I can archive shows that I record on the DVR.
