Possibly. The first question I would ask is precisely *what* errors  
you are getting in the recordings. Try "ivtvctl -a and you will get a  
dump of all the encoder parameters, look them over to see if anything  
looks whacky and if it does use ivtvctl to set whatever it is to some  
sane value.

If the parameter dump has no meaning to you feel free to mail it to  
me and I'll look it over when I get a chance, if I see something that  
would be of interest to the list I'll extract it and post it.
