Question : hundreds of mysql entries causing lag

is there anyway I can have this code load in groups of 6 rather than loading the entire database of over 900 at once. It is causing a lag effect in my flash swf thanks.

Answer : hundreds of mysql entries causing lag

It never loads it seems. Just a black screen. I don't know why that is happening but I assume you are just loading in the rss feed into the flash? you will have to debug the flash to see what is happening but I don't know enough about flash to help with that
