Eversince 10.4.2, my Dual 2.0 PowerMac has had two distinct issues. One is it seems to lock up more and more on video encoding. I have 2Gb of ram, 250 Gb hard drive. The second issue I have is the login in screen when coming back from sleep, never comes up. I have turned on "the require password when waking up computer from sleep or screen saver" It used to always work like a charm, and now since 10.4.2 whenever my powermac sleeps for a period of time, the login box will never come up. Instead I get the spinning beachball. I have done all I can do, repair permissions, lastest updates, unplugged external drives, isight, etc.. I am ready to re-install Tiger from scratch if I can't get this resolved.
Thanks in advance.

Try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokesrepair thread. Do everything in his link once a month and you'll keep your Mac running smooth.
