Hi all, I had at one point changed the resolution of how my recordings were being saved -- they are now 544x480. My primary DVD player won't play this resolution though -- I get vertical sync issues. Ironically, my daugher's $39 Wal-Mart DVD player will play them but my home theatre setup won't! The resolution is all that I can see being the problem. I want to make it true NTSC with 648x486. I also want to try some of the other NTSC sizes like 720x486 and 720x540. Can someone point to where I can find this and whether it would be difficult to change? Thanks Norm
