You can maybe use a
perl-script/python-script/ruby-script or similar to convert your hexdata to a
file that can be read into ethereal.

If you just want to analyze a
few messages you could use text2pcap to convert the octets to a file
in libpcap
format.
http://www.ethereal.com/docs/man-pages/text2pcap.1.html
<text2pcap -u
1999,1999 test.txt test.pcap
test.txt is the infile and
test.pcap is the outfile. I have enclosed a sample with two H.245
PDUs.
You can then mark one of the
packet and use "Decode As..." and then select H.245 in the list of
protocols.
Actually it is not normal to
send H.245 directly over UDP, but I used this feature to basic test the H.245
dissector.
