My first dive into HTPC was with W7 RC1 just a few weeks ago - and so far so good. It has a very "TiVo Like" appearance and is fairly snappy on a e6420 @ 2.8GHz. I have 2 cards for 4 tuners (Happauge 2250), and it handles season passes w/o a hitch. I don't use any "extender" type devices - the HTPC is directly connected to the A/V system via HDMI, and is controlled from a Harmony One remote.
I have run into a few small bugs and/or complaints I'd like some feedback on:
Sometimes if you cange channels and attempt to switch to a channel that is already being recorded in the Guide, it will tune this channel to an available Tuner, and the "live buffer" starts at that point of the show - opposed to tuning in the tuner that's ALREADY RECORDING that channel. Otherwords, sometimes if I want to change a channel, and then go back to a show that is being recorded and rewind what I missed, I'll have to find the Program in the "Recorded TV" section if I want to rewind it. Pretty annoying at times - and
this does not always happen (seems to happen more often the further into a recording you get).
Second - If I try to rewind a clip all the way to the start of the clip, my display goes black, and I have to re-start Media Center to get any video going. This seems to happen anytime I try to rewind to the first 30 seconds of a clip off the Live Buffer (or a clip that is currently being recorded). Using the mouse and manually dragging the Progress Bar to the beginning of the clip usualy works fine, but sometimes that methood will also cause my display to go black until I re-launch Media Center. It seems that I can never get the Live Buffer (or a show currently being recorded) to get the the very beginning of the clip - it seems to jump to 30 seconds into the clip - or causes the video to go black if you get within the first 30-seconds. There seems to be some issue with File Creation and the first 30 seconds of the clips - but if you play a clip from the "Recorded TV" section, it will play from the beginning of the clip just fine (I'm not 100% sure if playing pack pre-recorded clips still has the same issue with rewinding - but I know the Live Buffer has issues with rewinding to the start).
Lastly, if I let the Media Center Screen Saver come up (like if the HTPC is "Paused" for a few minutes), and try to jump right back into "Play", I get a 2-3 second Audio Loop that repeats endlessly (replaces the correct audio) until I close and re-open Media Center.
I have been through 3 different Audio and Video Drivers, and the same behaviour has been observed with all 3 drivers and even observed across 2 fairly different PC's. I'm running W7 RC1 32-Bit (build 7100 IIRC). Does anyone else have these issues? I'm hoping W7 RTM plus some driver updates will iron out these oddities, but overall I like W7 as a Media Center...
