Sorry you are having this problem
Im a little confused though. It works with Sony, It works with Panasonic , but not both at the same time, is that it??
I imagine a patch may come out soon to sort this problem if it affects enough people
I did recommend it in good faith having used it myself for AVCHD files from various camcorders with it. Namely Sony, Canon and Panasonic but not in combination.. I don't work for Sony
I would simply say the Sony support comment about using the trial version is a standard response to make discourage you from asking for a refund.. They might give you one if you tried
To be fair using AVCHD from 2 different brands of camcorder ( as seems to be the case )is a little unusual and potentially unexpected.and untested
Up till March 2007 there was no AVCHD editing software at all
As for AVCHD not being an open standard , We always knew than on here that the specification was broadly uniform but not the individual codecs. Also where they were encoded at different bitrates using them in combination may confuse the software
but it is a bit hard on Sony that Panasonics version has Issues with thier software
in combination with Sonys AVCHD
Niether company is admitting fault and in fairness to Sony thier software division is different to Hardware so the software issue isnt to do with with alienating Panasonic customers
Panasonic itself doesnt offer any software solutions though , does it?
Even Pinnacle Studio 11
without an update patch did not work at all with Panasonics AVCHD and may well not work with a combination of Sony and Panasonic
I wonder if you can used than in combination if you run the Panny AVCHD thrrough Nero vision 5, output it then try it
Otherwise just edit them separately
