mx record change doesn't show up in mx lookup

Greetings-
I made an update to my mx record to point to a new mail server.  However, I noticed there is an SPF entry.  Could this prevent the new record from being propogated?

MX Lookup does not show the new entry.  I'm also wondering how long before the change is propogated.  

Many Thanks,
Craig

DNS change propagation times depend of your time-to-live (TTL) setting in your DNS record.
Have you tried this before and check ttl value. If ttl expire and record is still unchange, there is problem in propagating.

C:\Users\xxxxx>nslookup
Default Server:  google-public-dns-a.google.com
Address:  8.8.8.8

> set type=txt
www.google.com
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

google.com
        primary name server = ns1.google.com
        responsible mail addr = dns-admin.google.com
        serial  = 1522201
        refresh = 7200 (2 hours)
        retry   = 1800 (30 mins)
        expire  = 1209600 (14 days)
        default TTL = 300 (5 mins)
> set type=mx
> google.com
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

Non-authoritative answer:
google.com      MX preference = 30, mail exchanger = alt2.aspmx.l.google.com
google.com      MX preference = 10, mail exchanger = aspmx.l.google.com
google.com      MX preference = 40, mail exchanger = alt3.aspmx.l.google.com
google.com      MX preference = 20, mail exchanger = alt1.aspmx.l.google.com
google.com      MX preference = 50, mail exchanger = alt4.aspmx.l.google.com
