Dear Mehdi ,

even my reply is way offtopic now , if i were you then i would searched the Google.com for my answer , my starting term would be "compress movie"
there are many questions in my mind (not specifically related to 8052) that i'm sure many of the users here have had experience on that matter ,but because here is the forum about 8052 family i am not supposed to ask them .
so try to get your answers from the right place,fortunately there are many message boards across the 'net each dedicated to a specific field.
consider a time when someone asks a question like 'how can i make a new dialup connection in windows ,so i can connect to the internet and post my replys from my home PC to this message board ?' here.
how do you feel when reading such a message ?
don't you feel that this question is not related to this message board ? and this would make you vote as non-specific. this voting can prevent users from asking their non-specific questions more around here ,so discussion reamins focused on the main topic '8052'.
it was better if you'd have asked how to do a movie compression along the thread where you've had started your original question or refered to the link that your initial question has been asked in your FIRST post in THIS new thread.

- about the video compression if you're using Windows XP ,so you can use windows movie maker which is integrated (Start>All Programs>Accessories>Windows Movie Maker) to your windows and easy to use.it gives a resonable quality/compression ratio.
also refer here http://www.videohelp.com/ which has a complete guide on movies and their compression and more . refer to the tools section and then you'll find many tools to compress your movies.

- 'Aryan Pour' dictionary is the really crap one that anyone can get(here in IR). unfortunaley due to the nice packaging and availabilty, people think it's the best. in good cases sometime you'll find words that their meaning is the word's third meaning in the first place! and sometime even wrong meanings !, and many use their dictionary as a refrence ,maybe such as your 'Saeb Soft Dictionary'. use 'Haiem' dictionarys . for english to persian use Babylon which is really easy to use with farajbeik (english->persian)glossary (contact me for more info on this) also along the Babylon englsih to english dictionary (www.babylon.com).
