MBAFF Interleaved Fields

With MakeMKV and FFMPEG, I've copied my Doctor Who Blu-Rays onto an external hard drive which I have connected to my Roku. Season 5 works perfectly because I was able to deinterlace it as well as convert it from VC-1 to MPEG-4. Season 7 works perfectly because it wasn't interlaced. Season 6 on the other hand, doesn't play correctly. Well, it plays, but when I play it on my Roku, I tend to see blue fuzz on the lower third of the screen.  The copies of these Blu-Rays play fine in VLC, but when I try to watch them on my TV via my Roku, I frequently see the blue fuzz flickering on the bottom third or so of the screen. With the help of MediaInfo, I was able to find out that even though these files are MPEG-4 files (OOTB), they use MBAFF interlacing. I tried deinterlacing with Handbrake (Decomb/Bob), but that just made it worse by adding frequent pixelation to the problem. What can I do to solve this blue fuzz problem?

By the way, here's the output from MediaInfo:
