I had the no video problem mentioned in the original post.  I discovered
that with ivtv 0.10.0 there's a new module option PVR-350 users must use
with the ivtv-fb module, "osd_compat=1".  That fixed the problem for me.

See http://www.mail-archive.com/ivtv-users@ivtvdriver.org/msg05748.html
(for example) for the announcement of this change.
