vista itself has hefty hw requirements, so some of it could be related to that. it's also important to remember that WMC on vista isn't as mature as MCE on xp. Think about how stable MCE was pre-rollup 2 or pre-2005; WMC is much better than either of those.
126.96.36.199 is more responsive than the previous vista builds, but I never saw perf bad enough to cause concern pre-188.8.131.52. If you're having issues with performance it could be a driver issue, assuming you have competent hw. Some builds of the Nvidia drivers (mobo or video) were complete crap.
My system isn't a high end system, but the performance is perfectly fine without DVRMSToolbox. There really does seem to be some sort of connection between the slowdowns and DVRMSToolbox one way or another. Note that we don't notice any performance affect when recordings are being analysed (even when simultaneously recording another show and watching yet another one), only when being played back after analysis do the remote control/keyboard/mouse click slowdowns occur. DVRMSToolbox is configured for a default of "idle" priority.
I noticed a few additional "clues" over the past 2 days:
1. If, instead of exiting Media Center when it becomes very sluggish, I watch a live TV show, Media Center immediately starts to respond quickly again. When I then watch a recorded show that has already been processed for commercials, Media Center starts to get sluggish to remote commands again. Note I only tried this once but I will try it again later.
2. If I keep struggling with Media Center long enough and keep forcing the commercial skip to back up and re-skip commercials, eventually the entire system completely stops responding to all commands. The keyboard, mouse and remote control stop responding and the current TV show sometimes keeps playing without any way to stop it. I ended up pressing the reset button on the computer to force it to reboot a few minutes ago. There are no errors in any of the logs, except for "The previous system shutdown at 5:57:34 PM on 03/08/2007 was unexpected." and "The LcdWriterService service hung on starting.". The only "warning" in the logs is "Recording of Avatar: The Last Airbender began as scheduled on 08/03/2007 17:28:11 and was interrupted when the computer lost power or experienced a temporary failure."
Can I get on the list and give 184.108.40.206 a try? Obviously nothing DVRMSToolbox does should be able to stop the system from responding, but again, my guess is there is a bug in Vista or certain drivers that DVRMSToolbox brings out on certain systems. Maybe 220.127.116.11 will help in our situation???
BTW, here are my system spec's: Processor: Athlon XP 3200+, Video card: X1950Pro 512MB, Video Driver: Catalyst 7.7, Motherboard: ASUS A7N8X-E Deluxe, TV Tuner: Hauppage PVR-250, RAM 1.5GB, Storage: 1.5TB, including 640GB RAID 0 (SiI3112A controller) with 2x 320GB SATA drives for recorded TV. Other than this issue (and the glitches with VFD display getting garbled every now and then), the system seems to be 100% stable and fully functional. It will even play high end video games (half life, etc.) while recording TV without any issues. The only time it ever stops responding is when watching Recorded TV.
Those of you with the same issue, can you post some info on your system?
For those of you that don't see any remote slowdown at all with DVRMSToolbox installed, what are your system specs?
