Considering replacing VCR as recording (timeshifting) device. How would you rate Tivo's best record quality against the best quality of a standard VCR? Better? Much better? About the same? I also wonder about PQ of various PVR units. I've heard it said that Replay is better than Tivo. Honestly, I intended to skip the standard PVR's as I thought at this point in time I'd be looking for a HD PVR but the tech is moving much slower than I anticipated. So I'd like to hear your opinion of current PVR's. Viewing on a 65" RPTV.
