In my opinion the LITEON is utter crap. I have no problem with LITEON as a DVD burner, but for DVD recorder I don't like how it is built.
For some reason it seems they are poorly insulated, fan / psu somehow causes interferences, sync issues, poor video quality, etc......and poor TV tuner.
I have gotten many LITEON DVD recorder models too and was disappointed with the quality compared to the original. I think too much filtering is used on the video......the tv tuner portion sucks too IMO.
I know for a fact not ALL LITEON recorders are bad - some are better, but the ones at Costco, well are the affordable ones, are average at best.
After doing a lot a research I have gotten myself the Toshiba DR-4 and could not be happier. It is QUIET, good fan, no interference/distortion, good clamping, no green tint or other anomalies, ability to control IRE for both input & output among many other features, including one of the best menu templates I have seen - You can choose among many colour menu styles, you can change thumbnails to the images you want, you can edit, it supports flexible recording (between 1h-2h using timer rec) and much more...... It's TV tuner is CLEAN, it has a frame syncroniser, it locks on to very poor video and maintains lipsync perfectly - There were reports of the DVD recorder falsly detecting macrovision on poor tapes. Personally I have fed the worse kind of VHS tapes to this unit and it has never failed on me. The build quality is sturdy, the connectors are rock solid and very durable, unlike the flimsy design of the liteons. I would not hesitate to recommend this one.
