Given the issues with the XL4, what are the opinions about what to expect with the 6 tuner Premiere Q? I'd love to have a 6 tuner and would gladly pay for it but cringe at the risk of issues that XL4 owners have gone through. BTW, this is not a Tivo bash. I used Tivos for a long time and love them. I only paused because of MRV dead on TWC. Streaming cured that so I'm on the edge of investing in new Tivos again. Just researching very well before dropping a couple grand on new Tivos.
