I have just switched to Direct TV from Dish because of good Direct offers. My installation will be in a week+, DTV DVR R15. After reading reviews elsewhere and R15 questions/comments on this forum am I wise to have chosen the R15? There seem to be many problems, e.g., freezing, not recording, playlist problems, etc. I was considring upgrading w/Dish to their dvr 625, then came the loss of my distant channel feed and Direct's promos. Any comments would be appreciated while I have time to rethink/change my order. Thanks.
