I am capturing TV using a Pinnacle DC10+ card fed from my cable box. The card captures in MJPEG format natively. I convert the output to MPEG2 (PAL) format using the Mainconcept MPEG2 encoder and burn to DVD to watch later. I also record TV shows on a Hauppauge WinTV PCI card using IUVCR and the PICVideo MJPEG codec (seems to give the best disk space/quality compromise) and then encode them to MPEG2 format

I am finding the following interesting behaviours

1. Playing the DVD on a TV is fine though for some reason on one of my DVD (http://www.mustek.com/html/prod_dvd/v56s-2/specs.html)
players the picture flickers a bit (sort of like a mild version of not having encoded with the right field order). This flicker only occurs on the DC10+ recordings, not the Hauppauge which is really strange

2. Playing the DC10+ recordings on my Skyworth 1050P DVD player set to output progressive PAL output on a Sanyo projector shows interlace combing artifacts which I can't quite understand since the Skyworth is capable of processing 575p and the projector can display it. If I de-interlace the picture first the combing disappears. Playing the Hauppauge recordings doesn't show these combing artifacts, even though the video has not been deinterlaced

Any ideas?

Thanks

Larry
