I asked Sony if I could use the MSA-128S2 256 Memory Stick in the TRV-340 and they said it was possible. I asked them directly if it would record longer than 15seconds using the 320x240 image size and they assured me that it is possible. Well, I finally received the chip and tried it in my camera. No luck. Still only recording for 15 seconds. ( If I record in the 160x112 image size I get a whole minute. This also does the pictures as an MPEG. So I haven't found a way to combine all of the 15 second clips into a full feature. Any help wouuld be greatly appreciated. The family and I will be goint to the Grand Canyon in 3 weeks and I was hoping to be able to record this so I can burn a DVD for the rest of the families. Regards, Mike
