This has happened to me twice now in the past 2 weeks. I have the show KillJoys on the SyFy Chanell set up as a series recording. No problems until 2 weeks ago. The problem is that the show appears to have recorded, but there's no video or sound. Although every now and then a commerical plays just fine. I also tried playing this recording using Fios TV on my iPad, but same results. All other recordings including series recordings are working just fine.
As to why you can't record the show(s) anymore, perhaps FIOS TV is now honnoring DRM?

Try picking a random show that is on and hit record.
The play it back. Does that work ok?
