The Malaysian VCD set, which is official**
, is very nice, if you can find it. Malay subtitles that cannot be removed, soundtrack and credits in English. A single disk for each story, and the stories are presented as on TV, in separate (rather than conjoined) episodes. A few Malay commercials before each story begins, between episodes and before the end credits of the last episode.
From descriptions I'm reading here at Tintinologist.org, there may be more than one Chinese DVD set. Apparently all are bootlegs, based on packaging imperfections, but the one I have, in the yellow and blue box, patterned after the single-disk French releases (that say "2 adventures integrales" in an upwards vertical string along the left margin) is impressive enough to make you doubt its inauthenticity. (There's a part of me that STILL thinks it may be legit.) It contains 11 disks, not just 10 (the eleventh contains the Belvision original film LAKE OF SHARKS), it's region free and the disks are of reliably playable quality. Optional subtitles in several languages, soundtracks in Japanese, Chinese, French and English. Credits are in French. I won't endorse it or encourage your buying this DVD set, but should you find it along the road, thumbing for a ride, you might consider slowing down the car a little ...

The Malaysian set, unless released by Apple Tree Films (of Singapore), is bootleg. See this thread for more discussions on the VCDs
