Thanks for the feedback. Ya, I guess I am now assuming my cheap filter isn't up to the task. I will have to get a better one.
The camera is modified though as the normal Canon filter has been replaced by clear glass (for astro shooting) so I can easily se an image on live view and even an image somewhat through the viewfinder with the Polaroid version of the IR filter installed. So I am going to try a better filter and see where that gets me.
Another-mikey, a lot of us use the Hoya R72 for IR work. After we get frustrated by focusing on something at f8, then putting the filter on, and then taking a 30 second exposure, we have an old digital converted to IR. It is much easier with an IR modded camera. You get much faster exposures, handheld. Youcan focus easily because you can see through the VF.
