As a DM I've seen players fudge rolls on numerous occassions. Usually it is not a problem - you know, a very infrequent intentional or even unintentional flub. I just let it slide. Life's too short for me to get worked up about it.
However, recently I was playing with a new group and noticed one player was consistently rolling "too well". I wasn't DMing at the time, couldn't see his rolls and I just chalked it up to luck - no one else seemed to care.
Next, I DMed a game with this same guy. Then the cheating really got out of hand. So much so that he started alienating other players with it. He constantly insisted on rolling untrained skill checks and nearly every time his roll would somehow bury the trained PCs (it was a low level start.) So I started requiring a "task leader" for all skill checks and any other rolls were just considered an "aid another" not a competitive roll.
I tried to indirectly mention this in my weekly email updates to the players. That worked for about 1 session as the guys dice suddenly "cooled off". But game after that he was back on it.
I began to see a pattern and so I stopped giving him DCs prior to the roll (because he often wanted his roll to sound "just good enough" but not "too good".) I also devised skill checks which required multiple success in a row just for his PC, which made cheating discreetly more difficult.
I also compeltely stopped giving his PCs any benefit of the doubt when it came to MY dice rolls. Normally, while trying to kill the players, I'm secretly rooting for them and I may occassionally fudge some dice for them. I didn't target him mind you, but I held absolutely nothing back on the guy. He was always charging into situaitons (playing party hero and assuming his fakery would save him) and I made sure he knew he was in over his head every time.
Besides that, I didn't try much else because I no longer game with that individual and I knew I was going to be parting company pretty soon anyway for a multitude of reasons.
Long story short - your DM has probably noticed. If you feel uncomfortable dealing with the guy, mention it to the DM. He may have some ideas on how to deal with it. At the very least he can just say all rolls need to be out at the table's center.
