Yes, both.  All the basic features of the hardware are supported.

Are you referring to the fact that the EyeTV software bundle was sold with
only MPEG1 and MPEG2 support?  MPEG4 was made available earlier this month
with EyeTV 1.7.  The hardware sold in the PC and Mac bundles is exactly 
the same.

Something like that.  MPEG4 decoding certainly takes more work than 
MPEG1/2.  Also, the TV402U has no audio encoder in hardware, so 
compressing the sound is done on the host CPU.

If you asked Plextor this, they'd probably have a good answer.  I've never 
played with the Windows software.  -Nathan
