Comment 21 for bug 229949

I have tried many configurations of the guide -- less columns/rows, different shading methods, different themes. The result is the same universally -- with Bob deinterlacing enabled, the guide is almost unresponsive, but without it, it works beautifully.

I have been using the patch I posted above now for the past month, and when deinterlacing is disabled prior to running the guide (which is what the patch does), the guide becomes extremely responsive again, even more so than it used to before this was a problem in the first place.

My recommendation would be to fix the problem by doing just this, as it not only corrects the issue, it improves the overall responsiveness of the guide itself over and above how it was before the bob deinterlacer started causing problems. The problem with the filter should also be figured out (I haven't been able to make any headway in this), but at least disabling all deinterlacing while in the guide seems to work very well.

And again, nothing short of this has help the situation while using Bob. Only switching to other deinterlacers / turing deinterlacing off entirely has made any difference without the patch, and using something other than Bob isn't really an option for me, as it is the highest quality and lowest CPU impact of all deinterlacers on my machine.
