Cuesheet issues

[iPodVT]

Context:
ipod6g - Rockbox v4.0.
I recently purchased a multi CD set of piano concertos, with each complete concerto being one unified track (approx 30 min in length) instead of the usual arrangement with each of a concerto's 3 movements being a separate track.  This makes navigating between movements unwieldy at best, so rather than editing each concerto's track file into three separate track files (e.g. with an app like Audacity), I thought I would try out using cuesheets.  I created the corresponding .cue files and it seems to potentially be a good solution but for a few issues.

Issue #1:
The first and most significant issue involves jumping to a track's cue points via the FWD and REV buttons.  When the FWD button is pressed while the current track's position is within any cue segment other than the track's last segment, the track jumps to the end of the current segment rather than to the beginning of the next segment.  For example, I have one track file with the following 3 indexed cue points (expressed as mins:secs:frames):  00:00:00, 17:10:00, and 21:55:00.  When the WPS shows that the track is currently at a point within the 1st cue segment and I press the FWD button, I would expect the WPS to jump to 17:10:00, but instead it jumps to 17:09:00.  If the WPS is in PLAY mode, it's not a problem because it will play right into the 2nd cue segment at which point the Now Playing and Next Track info gets correctly updated to the titles of the 2nd and 3rd cue segments.  But if the WPS is in PAUSE mode, the Now Playing and Next Track info do not get updated because the track is apparently still considered to be within the first cue segment.  As well, pressing the FWD button again has no effect because Rockbox jumps to the end of the current segment rather than the beginning of the next segment.  If the FWD button is pressed while the track is within its last cue segment, the WPS correctly jumps to the beginning of the next track.  But if the REV button is pressed while the track is within its last cue segment, the WPS jumps to the end of the previous cue segment which results in the same problem as specified above if the mode is PAUSE rather than PLAY.

Edit:  'REV' should have been 'REW' (as in rewind, not reverse).
