Not only pointless, but a thread like that would never end up in a good way, this forums are supposed to be for helping the DSTT community, not for flaming it or the product.
I mean, i understand that you have problems with your DSTT card, but coming here declaring the DSTT to be pure crap because you have problems with it will just open a Pandora box, and it's not the way to find help either.
My suggestion is try to exchange the card from where you got it, i've never had the problems you are having, The only game i actually had a problem was Contra 4, and it was easily fixed by renaming the save file, plus i know some people with DSTT's and they are in the same boat as me.
I know it's a pain. i have been through 6 xbox 360's myself, but if you have to exchange it, there is nothing more that you could do.
