i am new to the fourms and i didn't know where to put this so i just put it here.

i have an easycap dc60 and i got it working recorded a few videos and the audio was lagging at first, i fixed that problem but i can only record in avi in ulead video studio if i try to change the format it just changes back to avi and i dont know why or how to change it any other way. also if i go to file, prefrences, and try to change something and click ok sometimes it says there is an error and it needs to close. (it depends what i try to change) please help i really dont want one 10 min video taking up 9 gb so thanks for your help.
