Do you recommend that I use h/w?
H/w compression on DDS-4 is a bit feeble, so it may be better to stick to s/w compression if you have spare CPU cycles on the fd. That's the reason I asked, because the h/w compressed size can sometimes be larger than the uncompressed size, especially if you have both kinds of compression switched on! __Martin ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
