I am thinking of switching from a competing slide file program and will download the trial version of PTE. To be able to properly evaluate the program, I would like some advice on the quality of files I should use. I always shoot in Raw mode and convert my photos using Lightroom. I am aware that higher quality output would be using Blu-Ray but for now I will be using standard DVD output. The slide show will be viewed on a HD TV with 16:9 format. My camera has a 4:3 format so I can create any size jpeg files such as: 1280 x 960, 1900 x 1425, 2320 x 1736 etc. These can be 180 px/inch allthe way up to 330 px/inch. So my question is what size and resolution do you recommend for DVD output and would that change when I burn to Blu-Ray. Thanks in advance, Leo Reinhard
