HI , the Sony HXR NX5 works fine, I have the camera since May and it works just fine,I just had recently a small problem when my sdhc card cat. 6 had a breakdown,due to some chain reaction of my hand 😉 but I could get 99 percent of my files back with a program called cardrecovery…. so no worries about that.
I never had any problems losing any footage during shootings. The HXR NX5 works pretty reliable.
According to a SONY SPAIN TECH-SUPPORT ( i live in spain) the warranty +extended is only valid when you buy the HXR NX5 in the designated selling area…e = europe, p= southeast asia
I think the compact flash are more for foto cameras… I use for my hxr nx5 a sdhc integral ultimapro card cat.6 !!minimum!!! and a sony memory stick produo mark2…
I hope this helps you a little bit in your choice
