WD TV Live owner confused about upgrading... Please help!

Thanks for the reply.
Is Plex similar to the other PC based Media Center programs?

I have the PlayOn streaming program already, but the problem is my PC is too slow to transcode 1080p MKV streams.

Please correct me if I’m wrong on this, but I’m assuming Plex handles media the same way as the others, as in it doesn’t use the processing power of the Roku to decode anything, but instead relies on the PC/program to handle the decoding/encoding.

The Roku is more than capable of decoding these formats at high bitrate+1080p resolution, but my PC is not.
