DVDrip and transcode work fine for me under 64-bit. While there are issuse with 32-bit only codecs, they can be worked around in multiple ways, including a 32-bit chroot environment. Try adding the following for video output - "-vo sdl" It solves some of the issues. > - regarding audio, 64bit is not an issue.

Though, the Opterons do transfer a full 64-bit word containing a 32-bit value for each audio packet. In general, I've not seen my dual Opteron to be slower than the dual AthlonMP I ran. Converting to ogg with grip, is faster on my dual Opteron system. > - standard desktop applications, as far as I am concerned, heavily rely on > OpenOffice.org and that is still 32 bit Desktop apps are fine at 16-bit.

At 32-bit, one can only run 32-bit apps. And 64-bit apps will take advantage of the extra register set. A 64-bit kernel provides a faster os due to being more efficient, and having access to the extra registers. In gentoo the make.conf CFLAGS becomes - "-mach=k8", while for 32-bit, both "-mach=k7" and the USE flags - mmx, sse, sse2, (perhaps) sse3, 3dnow, and 3dnowext, all need to be set. Otherwise, your performance suffers when doing video. Bob - -- gentoo-amd64@gentoo.org mailing list
