Yes, it is due to the multiple lines. Try

channelBlocks = Regexp.new( 
 '<table width="132" border="0" cellpadding="0"
cellspacing="0">(.*)</table>', 
 Regexp::MULTILINE 
)

Watch out for greed and nested tables, though. 

I gave up on trying to make the literal Regexp work, escaping things by
hand is a real chore. :-P
