Are you in the SF Bay Area? I ran into this problem starting around February or March of 2013 (IIRC). Overnight my HD recordings went from ~6GB/hour to 18GB/hour. I made a few calls to tech support but they (obviously) had no idea what I was talking about and didn't ever transfer me to someone who knew enough to address the problem. I finally gave up because I was moving in a few months and it wasn't worth my time.<br>
<br>
Are you also seeing recordings fail? I had a number that did that because Myth wouldn't get the right PMT/PAT packets within a given deadline (they were buried in the flood of NULL packets) so I had to hack around that. If you're seeing that I may still have the scripts sitting around.<br>
<br>
If you ever do track down what the root cause is I'm really curious as to what it is.<br>
