Well, there is no free lunch. PVR-500 has an internal splitter, so the 
signal strength is halved anyway.

In fact, it can be worse than a separate splitter in some situations. 
Suppose that you want two tuners for MythTV and a VCR (or cable box or 
plain TV or something).  With two separate tuner cards you can use a 
3-way balanced splitter with 5.5dB loss on each leg. With a single 
PVR-500 you have to use a 2-way splitter (3.5dB loss on each leg) 
combined with the 500's internal splitter, so the signal loss for each 
tuner will be something like 7dB (on the other hand the VCR leg will 
only have the 3.5dB loss).
