Thanks to Ongkun for pointing out that Rak Haeng Siam is now available (illegally!) on YouTube at http://youtube.com/watch?v=hefnX2T2s60.  Original version, I believe, taken from the recently released VCD and DVD and posted in thirty segments, you can just link from one to the next.  No subtitles, either, so a good chance to practice your Thai.  But for you adventureous types, you can watch the whole thing on your monitor.
