Fortunately I am continuing to have almost bug free YTTV for the past few weeks. It works well now.For me the DVR functions were buggy at first. They seem to have improved in the past 2 weeks or so. Like now, "start from beginning" actually works most of the time. A few weeks ago it didn't, along with fast forward and rewind.
I'm still undecided on whether to continue.
So I'm going to stick with YTTV for the time being. Love the straightforward pricing and not having a contract term obligation.
