this is one of my favourite encoders for both mobiles and pcs...and the FILE SIZE PREDEFINE option in it is one of the most reliable and has amazing accuracy....however it fails to convert DAT files and other versions except 6.2.1 aren't as good. Even the advance ones..however i'll upload that very version.it's also good do make dvdrips.it can combine and convert 4gB dvd files into one 500mB files...similarly you can use it for mobile conversions as well...drawback is it's a 15day trial but it can always be used by takin the date back in pc or i'll post a trick to get it for 1year...it has large processing time which's a bad thing but the file size predefine option makes it one of the ultimates
