I agree that the capabilities of the Replay 4000 series are very cool. I would get a lot of use out of sharing shows between the two TiVo's in my house. The automatic commercial skipping is reported to be about 80% accurate. Not perfect, but good enough to make it a useful feature. And besides the current features, a networked device with full A/V capability, a big hard drive and updatable software has a lot of future possibilities. I really like how SB is positioning the product.

Unfortunately, Replay is still plagued by what is, IMO, a fundamentally flawed scheduling algorithm. It's explained very well in this TiVo vs. Replay review. In particular, read sections 13-15. These are the heart of a PVR. TiVo's paradigm is simple and effective. Replay's rules are byzantine and lead to a lot more confusion and missed recordings. Replay's fundamental design smacks of something that was too literally derived from one overriding use case.

If you are interested in Replay you should check out the board at AVS Forum.
