Tivo + Kmttg w/ biftool

I've been tweaking the encoding settings via handbrake/kmttg profiles a very small bit, with many thanks to the previous work of shelleye and txporter link 1 link 2. I've been discussing a bit with shelleye why my I get rebuffering a bit, and we think it's likely to be due to the fact that I'm trying to stream wirelessly. I'm currently using the "hb_roku_720_Detelecine.enc" profile and have reduced the bitrate to 2000.. so far no noticeable difference in quality and we'll see whether or not the rebuffering keeps happening.

So here's my current (work-in-progress) handbrake profile:
