No I'm not, the problem first started when it was just npvr. I'm well versed in the pvr 350 and I know that would cause a double sized recording and it would e 100% useless.
I know this is a really old post but I feel I have a little information. As suddenly as this problem came, it went. I went back to GB because it wasn't working. I let npvr sit. One day I decided I will fire it up. I did so and updated the listings, NPVR noticed it should be recording and did! It came out fine. So I have recently updated and I'm letting it do this weekend's recordings.
It did not start at first but that could have been due to a .net update, I restarted the service and so far so good.
