Further to my question, I got the manual (from Manual Owl [url=http://www.manualowl.com/m/Humax/HDR-FOXT2/Download/200968])
It says you can place bookmarks in "scenes" - not sure what that means. "Scenes" in DVDs are arbitrarily allocated 5-10 minute sections used for locating a part of the film. How would a PVR recording have "scenes"? If you place a bookmark in a scene, does the bookmark mark the exact place, or the start of the scene?
Apparently, the PVR doesn't automatically place a mark when you interruot your viewing of a recording. Ist that right?
