Cheers Marcus. I guess whatever card we use with adaptors, one or another problem is going to crop up sooner or later. Personally I have not had any problems with the old, or newer Transcends, I have been using them for over a year in the HM100 and EX1. I guess we are all in the same boat when it comes to using MxM/R. It is pretty much a case of using what we, or others find reliable. I will test for a while and report back any findings.

I have been using the Hoodman adapters and 32gig RAW cards with great success. Can overcrank all day long if necessary. I have two of them along with my 16gig SxS card and that's all I seem to need. Not one problem since I bought them two months ago.
Here's a link if you'd like to check them out.

Has anyone in the UK bought these Hoodman adapters and cards?

I'm not in the UK but I've had the same results as Bruce with the Hoodman 32GB cards. Long clips, overcrank, undercrank, quick start/stop... all seem to work as well as my SXS cards.

OK Charles, thanks. I might try them.

Having now had a proper amount of time with the ATP Class 10 16gb, I can't find any problems with the card. Is it just the 32gb card that is causing the media errors?

The 16gb Class 10 seems fine. Can't make it error by going to playback. No problems that I can see. I guess it's a 32gb problem?
