I'm using an iBook G4 as my main desktop and have a USB DVD burner, digital TV tuner plus external keyboard, mouse etc. I've got a cheap USB2 hub from a PC but whenever my TV tuner is running through it it starts dropping frames like mad if I move my mouse, but is fine if plugged directly into the iBook. Is it worth forking out for a 'quality' hub (eg something from Belkin etc, rather than a $5 no name tiny little thing)?

Possibly, but all the devices connected to the hub will have to share the bandwith of the one USB port. There is the possibility that the keyboard and mouse are dropping the speed of everything down to USB 1.1, so try only having USB2 devices plugged into the hub, and see if that improves things.

Quality is less of an issue here than how much bandwidth you have to share with that tuner. I'd dedicate a port to such a device and put mouse, burner, etc. on a different one.

After you straighten out your TV tuner, then get a decent quality USB hub from a "known brand" label.

I doubt the mouse being 1.1 is a real factor-I think it's more that you're sharing too darn many things on one port and thus sharing that one port's bandwidth-and cutting it down-whenever one of the devices needs to move data.

I'd agree with the above posters. It sounds like a bandwith problem more than a quality problem. As the others have suggested, putting it on a dedicated USB port straight from your iBook should solve the problem.

If the hub is bus powered and does NOT have it's own AC Adapter, this will also cause many, many (electrical) issues, especially with multiple devices being connected and in use all at once

There really is NO substitute for an AC powered hub
