Sony Vegas Crash while rendering to MPEG2

[Boogey]

My PC is equipped with Win 7 running on 2.2GHz AMD Athlon 64x2 Dual core processor with 2G RAM. There is almost 100GB unused space in my HDD.

I'm using Sony Vegas Pro 11 and trying to render to MPEG 720p which I'll buirn on a DVD.
I've finished editing an 8min video using multiple footage in m2ts and mov format. Both on 1280x720.
I used a few FSX provided in Sony Vegas.

I have no problem rendering to Quicktimemov or wmv or avi but when i attempted to render to mpeg2 Sony vegas crashed at all attempts.

I've tried to render to various MPEG2 options like DVD A PAL wide screen, Stream PAL wide sreen, HDV 720p but all crashed at various places on the timeline. What i noticed is they crashed at the points where SFX are placed.

Anybody have any idea what causes it? Is the PC spec not powerful enough? Do I need to adjust something in the customize rendering thing?

Does anyone have any suggestion?

Try disabling the GPU in preferences and see if you get any success.

(in Preferences, under the Video tab. There you will see
GPU acceleration of video processing. Set it to off.)
just try n error...if still crash just change it back..

Thanks for the response. I went to check as you suggested. The GPU is by default set to OFF. I tried rendering again anyway but couldn't get pass 6%.
There's no problem rendering the audio though.

Yessssssss! Found the solution and rendered successfully. For those having similar problems, here's what I did. It's actually very simple. Just get rid of the extra luggage. Go to Project Media and just below the "File" tab there's the lightning bolt symbol. Just click it and render as usual to MPEG2. First render the video and when completed, render the audio as AC3.
