I have one show I would like to burn to a DVD on my Mac. So that I can show

I have the TiVo network package, and Toast 10 but this doesn't let it happen.

On this page https://www3.tivo.com/store/accessories-software.do it appears to say Toast 10 will do it, but when I try I get a message saying I can't.

I've done some searching around but still haven't found a solution.

Any suggestions? As it's only a once off, I'm not really interested in paying any money for it.

Thanks

Charlie
