it's not a bug, MAME shows you the default resolution of the video chip, in some cases the chips can be reprogrammed to display different modes (think how many modes your PC can display)
avi files can't handle resolution / framerate changes mid-stream.
as stated, you can force an avi resolution with -snapsize 320x224, although it might still scale depending on the system (lo-res gets scaled to mid-res) and for games with framerate changes you'll end up with desynced audio.
hard truth is the concept of a 'resolution' is nowhere near as simple as it might seem, some games use multiple resolutions on different lines of the same screen, some different layers (think Galaxian and its starfield) so MAME has to approximate it all somehow to concepts people understand. Right now MAME is missing the overscan areas for most of these systems too, which while the games can't control the pixels in on a per-pixel basis, is still part of the video output of the machine, the modes people talk about are a massive over-simplification that MAME has perpetuated over the years.
