RMC just finished the download. Episode #2 is 93MB.
The native size is actually larger than the small version shown in the web page. It's about 640x480, although the bitrate really sucks (335kbps) and it's blocky because of it. They also used the On2 VP6 codec instead of the much-better H.264 Flash option. Ah well, you get what you pay for.
I suggest using the free VLC media player to watch it, for smoothest motion.

The free
Applian FLV Player denoises and deblocks the video a bit, but motion can be choppy and the video has this "fine pixellated" look to it.

The player you choose really boils down to personal tolerances in errors. (Personally, I hate both sets of errors, but I want smoother motion, so I pick VLC.)
Let's just say I won't be watching these on a large 50-60" display!!
