Whenever I try to select the EasyCap as a source of video in software (such as Ulead, Xsplit etc.) I will sometimes get a Blue Screen of Death that says DRIVER_IRQL_NOT_LESS_OR_EQUAL. However, sometimes it will run fine. I also sometimes get this error shortly after removing the device. I have tried reinstalling the drivers and running it without drivers, both with the same result.
Help would be much appreciated

I bet You have too old drivers for Your operating system.
The latest drivers for EasyCap DC60, EasyCap DC60+, EzCAP108, EzCAP116, EzCAP128, EzCAP148, EzCAP168 and Dazzle devices will be found from my support forum:
