No, there really is no way around your ISP installing bandwidth shaping equipment. The behaviour you are experiencing is similar to the one I had when my former ISP, Virgin, installed bandwidth shaping equipment.
One day I good download at great speeds the next I could not download a film clip to save my life. But, I could still download the odd MP3 and my IE downloads were unaffected.
However, your ISP Verizon may be using bandwidth shaping during peak times only, if that is the case you will have to retrict your downloading to overnight only, which is not too bad.
If you check this link you will find some people who believe they are being blocked by Verizon:
