I have a PCH C200 and A200 (recently re-housed into a metal case. Both work fine and, although there have been (and still are), some firmware bugs and restrictions, I have never had any problems watching my movies.
Are you sure that you want/need the C200? The A210 is significantly cheaper than the C200 and the only physical difference between them is the 5.25 drive bay and the lcd panel on the C200. The firmware is identical except that the A210, because it can't accommodate a BD drive, isn't licensed to play blu-ray discs, BD-J menus etc.
