Advertisements It could be that you're using the wrong image. Not all 6.4a files are created equal. They differ by host machine, i.e. a Hughes image differs from a Philips image differs from a Samsung image. I'm reminded of that now as an admonition that I first saw about ten years ago -- "don't be a moron" was the mantra. Don't try to mix software and machines as it either won't work well or will mess with TiVo's and/or DirecTV's communications with the machine. Beyond that, I would stick with 6.2a as that version still has HMO and MRV available as a hackable option with the Zipper. The only advantage I saw to 6.4a was the unerase feature, but TivoWebPlus has had that for years. To be sure of using the correct image, www.dvrupgrade.com is still your best bet. Sorry to see that Lou has doubled his price to $40, though. Still worth it to resurrect an old machine.
