Pro 8 c crashing, first time ever.

[Paul Kellett]

I'm trying to import some footage into vegas pro 8 c but it keeps crashing.
It only does it from my Sony hard drive camera, which records in mpeg-2 sd, only after i've loaded quite a few clips onto the timeline ,about 50 clips.
This has never happened before.
I can use my EX1 files fine, i can also use my Canon avchd files fine.
The little sony camera is about 4 years old and i've edited loads of stuff from it before.
It's just my little play about camera, this time i took it on holiday to record some stuff.
I tried to burn a disc from the footage using nero, even that footage can't be seen by my pc or vegas or even my dvd player.

the message i get when the pc crashes is this

Can anyone explain ?

I had problems like this with some old mpeg2 footage I was capturing from tape.
It was killing my Vegas 9c.
I eventually used Vegas 6 to capture and convert to cineform. It was stable but not all the data was retrievable. Btw, Vegas 5 is considered by some as THE most stable version. As you know, once you've got the footage stabilized with CF, it should easily import to V8.

I've found a workaround.
I imported 10 clips at a time and rendered them out as 1 mpeg-2 clip, then did another 10 and so on, so now i have about 6 new files and they work fine.
I've never had this issue before, do you think some footage was corrupted ?
Could it be something to do with a hard drive camera going through an airport scanner ?

My first instinct is always blame Dell. Even on Mac problems, it must something to do with Dell. My next instinct is to blame my other nemesis, Windows Vista. Were I a logical person though, I'd probably agree with your suspicions: corrupted footage.
