I just got this new 625 for my bedroom. The picture quality is actually a little bit worse than my old 3900 even though I used the same S-video cable. The difference isn't huge, but it's big enough that DVD's BURNED at XP speed from a Dish 3900 via S-video look better than video stored on the 625's hard drive even though there's no additional encoding there. The Guide really shows the picture quality difference the most. The guide on the 3900 was RAZOR SHARP, but on the 625 looks sort of dusty and slightly blurrier. I guess that they don't make em like they used to. Anyway, back to the original question, when will they give us CHECKDISK/SCANDISK and DEFRAGMENTER upgrades? All those excuses about not needing a defragmenter because of huge files is a lie. I use Final Cut Pro with GIANT files a lot of times and even if every file on the computer is over 1 GIG, the defragmenter still makes a HUGE difference in hard drive performance and noise reduction. I think the best thing about a Defragmenter will be the NOISE reduction it will have for DVR users. The best thing about the 625 is Dolby Digital and PCM capabilty. I wish they had DTS ES 6.1 Discrete on movies that have it, but beggers can't be choosers I guess.
