Indeed, please mail me a GTA02, and I'll repeat the test :) I think we'll both have to wait on FIC for that one. Hacking up some optimized video codecs would be fun, but I have so many other things I want to do and so very little time to hack on the Openmoko! -Steve ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I would imagine you're close to maxing out the read speed of the card at 1536 kbps? --- G O Jones ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

However, why do you think that the speed of the SD is close to 200KB/s, because it isn't. ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
