[mythtv] Mythweb errors

[rpage]

Now that Thor's back I figured I would post this. I don't know if
anybody else has seen these.  

I seem to get this error:

Fatal error: Call to a member function on a non-object in
/var/www/html/mythweb/listings.php on line 151

On the first sheet or two when I access mythweb listings. As well, on
the pages where this error appears, the listing is cut off after channel
14. Advancing in time a page or two seems to make it disappear (for
subsequent pages), but when I go back it reappears.

And I get this:

 Warning: mysql_num_rows(): supplied argument is not a valid MySQL
result resource in /var/www/html/mythweb/search.php on line 240

When I try and search. 

Any ideas?  I'm running yesterday's cvs, using PHP 4.2.3 under Mandrake
9.

Thanks,

Randy
