Hans - I will email it to you directly.  The debug info is about 400K,
exceeding message size limit for this email list.

Hi Rich,

Try adding 'ivtv_debug=511' to the ivtv module options. This should
provide (much) more debug info and hopefully help in giving me a better
idea where the problem is.

Thanks,

       Hans
