Axiom Home Page Forums General Discussion Technical Questions High Def on a DVR?

This is probably a real newbie type question - but I am new to hi-def TV. I have recorded some HD shows and when watching them later on - they definitely don't seem to be in high definition. Latest example is the PBS series on India.

Is Hi-Def lost when recorded? My TV (Insignia) and cable provider (Comcast) seem to provide reasonably good HD when an HD show is watched "live" (when broadcast) - but I haven't compared the same show live and recorded.

We plan to switch to Verizon FIOS TV service soon, but the question remains.

Thanks
