I just recorded a movie(Christmas with a Capital C) off TBN on dish and on Glorystar The one off Glorystar is too dark. I thought it was the movie but I just looked at the one off the dish and it is much better. My husband thought the Glorystar one is about 15% darker than the one off the dish. I have both dish and Glorystar hooked into a DVD recorder with RCA jacks and the recorder is hooked to the TV with RCA jacks also.
Have you tried connecting the Glorystar receiver to the DVD recorder using the higher quality Red/Green/Blue Component RCA video cables instead of the yellow composite? This connection type will provide better video and would be a good comparison of video brightness between the two connection types.
