Ponyo wasn't handled well by IVL, but all the other releases to date have been excellent. The one IVL release that you should strongly consider is Laputa. It's been shown that the US release coming out on May 22 is dub-titled (i.e. it passes off the adapted dub script as the literal translation to the Japanese audio track), but the HK BD release has the exact same 1080p @ 33 mbps video encode and lossless Japanese DTS-HD MA audio as the expensive JP BD release, along with proper literal subtitles. The only thing it lacks is an English dub (it has Mandarin and Cantonese ones instead), but I'm a sub-watcher so it's no big deal for me. Here's a breakdown of the various releases:
JP: English dub, literal English subtitles, 1080p @ 33 mbps video w/o DNR, region-free.
HK: No English dub, literal English subtitles, 1080p @ 33 mbps video w/o DNR, Region-"A" locked.
UK: English dub, literal English subtitles, 1080p @ 26 mbps video w/ DNR, Region-"B" locked.
US: English dub, inaccurate dub-titles, 1080p @ 24 mbps video w/o DNR, Region-"A" locked.
