Thanks everyone.
I am leaning toward the R5000HD for now, but may get the Hauppauge HD-DVR sometime in the future since I want to be able to record multiple shows at the same time.
I only record SD shows and I have a few more questions:
1. Does the dishnetwork broadcast SD programs in MPG or mp4? If they are in MPG, the R5000HD may have slightly disadvantage for me since it records original MPG stream. I need to do extra work to convert them to mp4 to reduce the file size.
2. For the hauppauge hd dvr, if I record SD shows at 720p, will it have better quality than the original 480p source?
3. Are there any software out there that can edit mp4/mkv files directly without re-encoding? Just want an easy way to cut/remove commercials, join multiple clips.
