Yes.  The most important point about the PVR-350's decoder is that it 
can *only* be used with the PVR-350's TV out.  Since the PVR-350 isn't a 
true video card (it just has a framebuffer), there is no OpenGL or even 
X Video acceleration.  Therefore, if you try to play anything other than 
PVR-x50 recordings on the PVR-350's TV out (i.e. MOV, AVI, DivX, XviD, 
DVD's, etc.), you'll incur a *huge* performance penalty.  On my Athlon 
XP 2000+, I wasn't satisfied with the TV out on the PVR-350--except for 
PVR-350 recordings--so I'm using my 350 as a 250:  I don't even load the 
framebuffer module, and I'm using a GF4MX440 for TV out.

Therefore, I agree with Dave.  I wish I would have saved $80 by getting 
a PVR-250 instead of the $350.
