dshowserver r33 does not display properly on mythtv r15290

[GoogleCodeExporter]

This is a case where r30 works fine but r33 can cause either of these 2
situations:

1. Turns entire screen green and does not display properly,
2. No video, generates following output:

I am using CoreAVC 1.5.0 with both versions of dshowserver, although 1.7.0
has the same results when using r33.

A myth recorded h.264 stream that demonstrates the problem is available at
http://devzone.mine.nu/279_20080509202054.mpg.

The hardware is Athlon64x2, nVidia 6150 running nvidia driver 169.12, linux
kernel 2.6.25, 32-bit Gentoo.

Give the following patch a try.  I'll probably commit it to SVN soon, but I 
think it
may help the issue.
