thank you for the idm license. was really pleased to have won that.
i have thoroughly used idm the past few days and am really pleased with it. it had a few issues pertaining to flash after my internet explorer 9 upgrade but these were fairly quickly solved.
what i find most useful in idm is the flash video grabber feature wherein it can directly download the source video file from the flash video that is loading. i tried multiple video sites like youtube, yahoo and it works on the majority of them. it does not work with bbc iplayer however
i also tried site grabber and it works well. all in all idm is a must have tool.
