Replace mpeg2 WTV files with h.264 WTV

I know from the previous HDHR Extend tuner that the tuner recorded and streamed compressed h.264 video. My assumption was that WTV is a container file that could have any number of codecs used within, like AVI. Looking into it Wikipedia says

“Multiple data streams (audio and video) are wrapped in a container with the file extension WTV. Video is encoded using the MPEG-2 and MPEG-4 standard and audio using MPEG-1 Layer II or Dolby Digital AC-3 (ATSC A/52).”

…then adds…

“The format extends these standards by including metadata about the content and digital rights management.”

My modified question now is: Can MCEBuddy encode MPEG-4 / h.264 video into a valid WTV container including the correct metadata needed to properly function as a WMC file served from the “Recorded TV” folder?

I hadn’t known about the metadata and digital rights headers, so I assumed the h.264 video could be renamed, similar to the way .vob files can be renamed and used as .mpg files.
