With Gary's method, you put the event in twice and reverse the second clip.

You can also use a velocity envelope. Set the beginning to play at 100 and then set it to -100 and trim the clip to the right lenghth

"Velocity Envelope" - Right click on the Video event and select Insert/Remove> Velocity.

You now get a Line appearing running through the clip. This represents the default speed/velocity of the clip OR 100%, this equates to the exsisting rate of the clip. Pull the line upwards and the clip runs faster. Pull it downward and yes, it goes slower. Now, right click on this line and you can drop Points onto thisline and apply a % of speed relative to the otriginal speed/velocity. So, 150% would give an increse of speed, well, 1/2 as fast AGAIN of the original. Now you want to make it slower if you go to 50%, then the clip wouold run at 1/2 speed. Want to make it go into reverse? Then go BELOW "0%" into the NEGATIVE values and this will start to make the clip go into reverse!

You have much to explore here in getting a Velocity Envelope to work. Might I suggest you use the Online Help in V5, it is rather excellent.
