Ok- I shot HD footage from this new 2007 Sony HDR-UX5 camcorder. I uploaded the HD footage by S-video to the Panny EH75 from the Camera-Now we know it is not true HD this way but it is still a good feed for recording and burning a disc. I also loaded direct the same camcorder footage by USB to My Sony Computer with same camera software installed. The Panny DVDR killed the Sony computer on quality of the DVR-R burn quality. Not that close. When people say that computers can burn a better quality DVD-R than a DVD Recorder , I think they are smoking something illegal. However you may ask why I did not do s-video input on the computer- I do plan to try that- a lot of people do not have those ports - I do and will try it- maybe that will equal the playing field but s-video on a computer is unstable at times. Lets hope it is stable.

what speed did the PC burn at? a pc burning a high speed disk at high speed will inherently induce more small errors as a result of slight "wobble" and induced laser tilt of the fast spining disk.

On the other hand a DVD recorder burning the same media at a slower speed will have less "wobble" to deal with and hence more errors.

In terms of picture quality im sure the PC won hands down as there is no digital-->analog-->digital conversion going on.

life is what happens when you try to follow plans

HG, Just curious by your blanket comment without much detail.

Are you comparing final DVD VOB/MPEG files created on the PC to the DVD recorder? Assume you are.

Does the PC recording/capturing software have quality settings on its encoding to MPEG format? Did you use the same/similar recording quality on the transfer/encoding to MPEG format on the computer as that on the DVD recorder?

If you just used a default setting on the computer, even something like standard/better, record quality might have had inferior bit rates as what the DVD recorder is set at. May have to check out the final MPEG files with some player software to see final bit rates.

This said, not to surprising the DVD recorder produced better results from other postings in the past of problems with PC video production and complexity of it and producing less then satisfactory results without some major tweaking of its setup or without very good PC components.

I wouldn't think this was any factor in the quality of these videos because HG does not mention any type of disk problems on play back or the video being pixelated/broken up indicating a bad or less then perfect burn.

As long as the video copied over with no errors (which it seems to have done since none of the above was mentioned) then the speed would not have mattered. Only when it produces errors or a player cannot play back certain disks or speeds would it matter I believe.

It seems to me that that HG is saying that the PC picture quality was inferior to the DVD recorder, at least the final DVD VOB/MPEG file format of it. He does not make it clear if he had saved it on the PC first in some high quality AVI or HD file format and compared its playback to the DVD recorders which one might think would be better.

Clearly the comments of somebody who does not know how to master basic computer software. Give Procoder, MainConcept or CinemaCraft a 2-pass VBR job, and that Panasonic will be put to shame even more than normal. Even the basic $50 versions can do this, or the free/near-free encoders like TMPGEnc and HC Encoder. A good software encoder would put ANY DVD RECORDER to shame. Quite a few hardware encoders can too. I can only assume some piece-of-crap software like WinAVI or Nero was used on this computer "test".

Absolute "poopycock" (to quote my favorite Boston Legal judge).

The comment about WinAVI being trash I agree with, I wasted money buying that crummy program. Nero OEM 6.3.1.11 (which was bundled with my Lite-On burner)is fine burning software, although newer versions suck because they were crippled so they would not work with DVDShrink.

There must be some plus to a DVD recorder with a HDD or why would someone pressure the Asian manufacturers to leave out first component inputs, then this year, scrub the sale of DVD recorders with hard drives and ATSC tuners in the United States? The amount of time and the extra computer gear and software programs needed to make and master DVDRs on a computer is a chore many people do not feel up to. On the other hand, pressing a button to record a brodcast on a DVD recorder hard drive is right up most people's alley.

I've tried camcorder video input conversion on several different DVD recorders versus using AVI on a PC . Its very easy to do on the recorder and the results aren't bad.

It takes a LOT more "work" and time to do it right on the computer...
BUT if you do it right, the DVD recorder doesn't come close....

The devil IS in the details.

I'm with LordSmurf on this one....
