@Davextreme: Yeah, I know - but I've seen some 1080p iTunes files and they look awful compared to their BD counterparts but I suppose that if people are going to convert to this kind of shitty format anyway, it's still better to have a quality controlled encode from the original files out there.
@Adm. Kirk: Compare - you'll copy the MD5 checksum from the 1st post and then compare it with your file. I was introduced to this concept recently myself but it really is very useful for this stuff.
