It's been a little over 48 hours and it still shows as "Pending" - It's no longer in blockchain.info

Cant post

I have been waiting over 9 hours for this transaction to confirm:

fef2d4fbd92115082dc652a03dad81911b7789d26faa41c7fe739b691e50dbe6

The transaction is going from here: 1JyD47xXLzfrDW6vZrdLoTGwjqe3ACCKuW to here: 1BuoKuNkFDaTGxi34fes67iNWw7TXW7nm9

I see an address: 1MufqYB7hw6aF8aMwisPdSHzDoZQoz2Drc

From what I understand this is a "change address" and the funds are still showing in my wallet. I understand the funds will come back to me.

I have enclosed a .0001 fee, which is low, but still acceptable. So far the transaction is STILL not in the block chain. Blockchain.info says that my transaction is "medium priority" it is "within 6 blocks" - what does this mean exactly?  I also notice this transaction does not seem to be propagating (other transactions with similar kb and similar fees have been confirmed already) How long should I expect to wait and what can I do to either speed the process up or cancel it if it doesn't confirm?

I also notice another transaction: 4f42121b680d6c44a6c238b36d462b643a2b9cb6f65c4efa42c6108a81739a6b that according to blockchain.info has no confirmations, but my client says it has 11! Why?

Thanks!
