Well, the H.264 encoder used by Apple isn't at all bad - I've certainly seen much worse implementations (for example, those of Panasonic used in their 2009 720p P&S cameras like the ZS3 / TZ7). For that matter, deinterlacing the 60i footage produced by the HV30 is much more destructive to the image quality than using H.264 (and not HDV) in the first place. When played back at nominal (120/60) fps for fluid motion, there would be no point at increasing the sampling rate (44.1 kHz). At playing back 1/4 speed, it could, so that you could hear for example the sound of for example bats played back at 1/4 the pitch. Otherwise, it'd be pretty useless.
