MCC - RTC and ITV Tweak not available unless machine is configured as backend

This is the intended behavior as these are more interesting to machines with
backend roles. Can you please describe your use case for having these on a
frontend?

I would agree that the IVTV tweak is more interesting to a backend machine because it relates to the capture cards. However, unless I misunderstand it, the RTC tweak directly relates to the output of the video that I am trying to view via the frontend.

I would even go so far as to say that the RTC tweak is of almost no interest to a backend, and purely of interest to a frontend, again assuming I am understanding the tweak and it's need.

Further to my above comment, directly from http://www.mythtv.org/wiki/index.php/Frame_display_timing

"If MythTV will be using the RTC to time the display, it will usually request a high interrupt frequency, allowing it to time frames more precisely. However, unless MythFrontend is a privileged process, the highest frequency that it can request by default is 64 Hz. This is usually not sufficient for CRT monitors that are often set to a higher frequency, usually 85 or 100 Hz, as well as some LCD screens and projectors that can accept various frequencies, producing the tearing artifacts as mentioned earlier. The most common solution is simply to increase the maximum frequency that an unprivileged process can request from the RTC."

This indicates the tweak would be used to improve video output performance, more of a frontend function.

Ah point taken. It's a little late for 8.10 to fix this, but we can put a
fix in later for it.

Looks like released mythbuntu calls out the correct package in which this was fixed previously:
