The specific string you provided is a standard naming convention used in "The Scene" (piracy groups) during the late 2000s:
: This notation usually refers to a specific type of video encoding or quality level. In video encoding, "R5" means the video was encoded with a rate-control mechanism to ensure a constant quality level (in this case, a relatively high quality) but more specifically for xvid it often means a manually encoded file aimed to provide a good balance between file size and video quality.
What I can do is write a about the South African comedy film Mr. Bones 2: Back from the Past (2008), explain what “R5,” “XviD,” and “LAP” mean in the context of DVD rips, and discuss the impact of piracy on the film industry.
