Well, disassembling Flash files is not exactly confortable, but it can be done. Anyway, depending on the kind of info you need, you might be able to avoid disassembling completely, at the price of some reverse web engineering.
A Flash application usually communicates with the server using GET or POST (newer versions also handle XML data in the request, but communicate over HTTP anyway): thus, if the application receives the info you need as external data (which is very likely), you should be able to do the same.
I've had a look at the site and I'm not sure of where the "race program for the day" is; but using a sniffer revealed that "Bet X top dogs" under "What's up" menu link is not inside the app, but comes as text data in answer to a POST request: "POST /rx_asp/rx_getdogdata.asp", with data payload "req=topten".
So, no need to use Flash links for topten now:

%curl -d "req=topten" http://www.rosnet2000.com/rx_asp/rx_getdogdata.a
+sp
[download]

yelds this result:

topten=cruising,39773.55;face,38085.5;db,36317.38;Vikingsroc  ,36116.7
+4;annie91,34131.46;gb,33068.55;rr,29465.4;kka,29121.1;i1,24721.9;DRAM
+BUIE,20749.4

which is really easy to parse...
Good luck with your reverse engineering!
