Hi all, I'm running a borrowed copy of Vegas Pro 11 and I can't for love nor money get it to render properly. The person who lent it to me has been using it for a while with perfect results, but on my PC it just isn't playing ball. I've searched the stickies (and the rest of the internet) and tried numerous things but I can't get it to work. My system: Intel i5 2500k 8gb DDR3 HD6950 2gb Win7 home 64bit. Now the footage I'm using is recorded using a Hauggapuge HD PVR2 Gaming edition, I've recorded in both M2TS and MP$, and both come out fine in the Vegas preview but as soon as I render it, it turns out as a green screen with the odd flicker of the footage. This is what I've tried: GPU acceleration both on and off. 32 and 64 bit Vegas. With and without K-Lite codec pack. New install of Windows. Numerous render settings (MP4, AVI, MPEG etc etc). No matter what I do, I get the same results every single time. I should perhaps mention that in the preview in Vegas, the clip shows up as a green screen but this sorts itself out after I hit play. Having seen what people can do with this software, I was really looking forward to trying it out and perhaps purchasing it for myself but this borrowed copy is giving me so much frustration I might seek something else to keep me busy. If anyone has any suggestions on how to sort this out, I'd greatly appreciate them.
