Apparently both WNLO-HD and WIVB-HD are going exclusively CW and CBS. Nice thing is that more bandwidth will be allocated to their HD programming, but the downside is that reception of WIVB-HD 4.n is spotty for me at best. Over the summer I was receiving WROC-HD from Rochester more reliably than WIVB-HD from Buffalo.
Be in touch with WIVB by visiting their website; www.wivb.com
-- Scroll over "programming", follow the HDTV link, and send an email with your feedback. They seem genuinely interested to know what their audience is experiencing reception wise...
