Top of Picture Noise

[gussie]

Every recording I make with my Relisys RDVR250 DVD Recorder has a line disturbance along the top of the image - looks like a time code.

Even get it when just recording a VCR menu - see the images...

Do other DVD Recorders suffer from this?

I know you cannot see this on the typical overscanned TVs and of course you always get VCR head switching noise along the bottom of the image of a VCR recording - but a DVD recorder should not be adding anything like this to the top of the recorded image.

I never got this when capturing using a PC VIVO card - all I had to do sometimes was to crop the VCR head switching noise - but the top of the image was always clean!

However, the PQ is very good using SP (2 Hour mode) !

Also, am I right in thinking that DVD Recorder chipsets produce better quality on-the-fly encoding than any PC hw encoder (Ext USB or Card based) like the Plextor or Hauppauge products?

I'm just using this DVD Recorder to get the initial DVD+RW based mpg files, I then spend a short time lightly editing (no re-encoding!) on a PC, and then produce a much more compatible DVD-R version.

My Philips 985 does it on the botton of the screen. Never bothered me since it only shows up on my computer when I need to edit to re-author from the DVD+RW.....or +R if I had a brain lapse...

Thanks for the reply - but surely it can't be teletext when just recording a VCR menu screen with no aerial attached to the VCR.

I think it's just a glitch on the Cirrus Logic chipset used in this DVD recorder - it very much looks like a repeat of one line of video.

As I and others have noted you only see this when previewing on a PC.

But it would be good to find out what it is exactly.

It's not a glitch. This is standard overscan data, and a quite tidy little one at that. This looks like satellite tv data. Everything you have will do this. DVD recorders and capture cards ALL grab 100% of the data. You'll have to MASK it out otherwise (ATI AIW cards on ATI MMC have an auto-mask feature during capture, although they misname it "crop" too).

It might be space reserved for non-visible information, whether it is teletext, closed captioning, or whatever. My Liteon 5001 does it too...I'm fairly certain this is a common thing.
