With my first post here i have to thank you all for this wonderful site and for helping my poor spoken english comprehension

And now the sticky question:
i watched 3 seasons of Lost taking here english subs an pasting them to the most common version of the video files i found, and it has always worked perfectly..
Now i'm a Heroes addicted, but the sbus i use to take here are not in synchro with the files i get.. elsewhere

Now, I know how to synchronize with VLC, but the problem is i have to fix it about 5 times for a episode (due to the commercial breaks, i suppose)..
Is there a way to exaclty know wich specific version of the episode the sub are made for?
P.S. Sorry for my bad english
