I recently observe 3 problems when playing ISO DVD rips.
1. Widescreen videos (16x9) switch to 4x3 aspect ratio at some point,
which seems to be repeatable. I suspect it happens when a subtitle shows
up in the stream. See attached mythfrontend1.log output for clues. This
happens with Slim and VDPAU Normal profiles. One can "fix" this by
selecting H.Stretch from the Adjust Fill menu.
2. ISOs with several titles take a long time to start up, and also to jump
to the main menu. See attached mythfrontend2.log output, where the time
between 06:55:32 and 06:56:08 (36 seconds) is spent on the "Please
Wait...." screen.
3. Jumping within an ISO video sometimes has accuracy problems. For
example, pressing "50i" to jump to the 50-minute mark may jump to the
46-minute point (but a subsequent "50i" usually jumps to the right point).
This is unpredictable and often happens only during the first jump (if it
happens at all). This is especially unfortunate when it happens as a
result of the initial bookmark seek when playback starts. Through
experimentation, this seems to be a problem seeking to the desired frame,
and not a problem converting between frame number and elapsed time.
