The crc I posted was taken from the nds on the microsd card. Unfortunately I do not have any other microsd's to test this on. My md5 does match up with your's though (once again taken off the microsd card). I'm fairly confident we're dealing with the same file here, so it must be a hardware or 'os' issue. Just to clarify, I am using an r4i gold from www.r4ids.cn, purchased from lightake.com. I confirmed based on the pictures shown on the cn site that it is indeed an authentic card. I am currently running your wood v1.22 on a 1.4.1U dsi. I was having the same problem on my 1.4U dsi, so I upgraded to 1.4.1 in the hopes that it would resolve the issue. I can take a video of the freeze if you think it would help (or if you don't believe me :-P)
edit: reformatted the card, and at least I now have video after the opening cinematic. I see the zelda chick falling and falling, and my name is at the bottom in a speech box. But its really really slow. Could it be that the microsd card is bad? Its a bit of an old one, but I've been using it pretty consistently for a while now with no problems. I do have a brand new microsd on standby, but I was planning on returning it, since I came across a 'spare' one: my new phone came with its own 8 gig microsd, so I took my old phone's microsd for the ds.
edit edit: well, after a painstaikenly long time, I was able to get the skip prompt in the top right. I skipped this particularly pesky cinematic and am now in full control of link. I hope this issue doesn't recur with subsequent cinematics. I'll update if it does.
edit edit edit: Well, it seems that the problem still presents itself in an only minorly annoying form. Whenever there are small cinematics, such as at the end of the first dungeon when the red fairy joins me, or when I obtain the Phantom Hourglass, the game kind of haults, the music gets all garbled, and I don't see anyting. Eventually I get to see the cinematic at regular speed and with regular sound. At least I /think/ I get to see the cinematic. I dunno if it skips it and I just see whatever comes immedietley after.
edit edit edit edit: So I played until I got the northwest nautical map and saved it. Now when I try to resume my game I get a double white screen of death, with garbled music. Same music I was getting before.
