I don't  know why you guys are having so many issues. I just made my 3rd successful deposit in to my Mt.Gox account this week. Each time the money hit my Mt.Gox account within 1 minute of the MoneyGram going thru. I don't know about the other options but I can assure you the MoneyGram -> Mt.Gox is working just fine. I will say that when I fill out my form with Bitinstant that I use my Mt.Gox account name and not my account number and I have never had an issue. The only time I have ever had an issue with Bitinstant was going MoneyGram -> Btc.e.com and that was due to low reserves. Never had an issue MoneyGram -> Mt.Gox.
