H.263 / RFC 2190 has been deprecated and shall no longer be used. If it is still necessary, there is a plugin making use of a hacked ffmpeg library which you can compile from the OPAL sources. However this plugin is being deprecated as well, since the H.263-1998 plugin is being added RFC2190 support as well in the trunk of OPAL (you can also compile this plugin from the sources)

Yes. H.263 - 1998 is the same as H.263+.

To summarize the H.263 mess:
H.263 (no +) = H.263 1995/1996 (RFC2190)
H.263 + = H.263 1998 (RFC 2429 / RFC 4629)
somtimes you also find H.263++ = H.263 2000 (RFC 4629)
