If I have an ATA133 IDE controller with an ATA33 DVD-burner and an ATA133 Hard drive on the same channel, does it limit the throughput to 33Mb/second because of the presence of the ATA33 device?

It depends on the specific IDE controller chip, and how the BIOS is designed to deal with different speed drives on the same channel.

You can start by finding and reading the manufactures specifications on the specific IDE controller chip.
Intel, AMD, VIA, SiS, High Point Technology, Promise, to name a few.

Then, check with the controller card, or motherboard manufacture for their input.

I avoid this issue myself by either using motherboards with 8 IDE channels, or installing a PCI IDE controller.

This way, I can have my hard drives and removable media drives on separate IDE channels.

Most likely, yes.

Always separate your opticals from your HDs. Even if they were the same speed, transferring from one to the other would go slower than if they were on different channels.
