I got a 3575 in mid-October and I've been working my way through all these posts - lots of GREAT information - thanks, all. I wanted to report on what I ran into, and also see if anyone has any input on my remaining issue.
I purchased the 3575 at Walmart for $298 (one of 2 available) - it had an August 2007 pack date. I'm not real high-tech; I planned to use it mainly to record from TV to watch later and to play commercial dvd's (basically replacing a vcr/dvd player combo). Also for the tuner, so we could watch our cable channels on the HD tv (the only coax input on the tv was used by a tabletop antenna, which pulled in the local OTA broacast hd channels).
After playing around with it for a few weeks and comparing the results with what I've read here, I ended up with 3 basic issues: (fyi I have Cox "basic" - non-digital - cable.)
1) It consistently hung up at digital channel 121 on setup. I could get out of it by either canceling it before it got there, or turning off the unit when it was hung up. If I did the latter, it would keep trying to tune to 121, seeming to go through some kind of cycle, and every 30 seconds or so a blue screen would flash up. If I hit 'channel-down' on the remote continuously, I would be able to catch it at just the right time and then I could tune everything else normally. Never had to pull the plug with the cable like others had mentioned.
2) It pulled in a handful of digital stations from the "analog" cable, but it was missing at least 2 that I knew should be there (I could get them on another fairly new digital tv with - I think - a QAM tuner).
3) Couldn't get any closed captions on analog channels, either while watching live or hdd on recording. I read in the manual that there are limitations on cc's on HDMI input, but I tried on the component connection as well.
The Tech I talked to at Philips said they could replace it, but he recommended I exchange it myself since I had gotten it at Walmart. I was a little skeptical, since the only other units I'd seen had the same (August) pack date. I ended up buying a new one (same pack date but different Walmart). It solved all of the above problems! (With one small exception...), and I returned the orignal.
So now, with the new unit:
- no hang-up on on digital channel set-up,
- all the know digital channels as well as the standard analog cable channels work,
- I never did have any channel-loss problem (on either unit),
- and, I can use the cable pass-through to get the digital HD cable channels in (what looks to me to be) real HD - almost as good as I was getting from the ota antenna, and much better than the version that comes through the 3575 tuner.
Anyway, if you've read this far - can anyone see closed captions (either analog or digital) on programs you've recorded on the HDD? I can see them in the live broadcast through the 3575 tuner, but not on the HDD recording. I've made sure all the options on both the TV and the 3575 are set to show cc's. Interestingly, I dubbed an HDD program to a DVD and played it on another TV, and I could see the CC's then!
Hope all this helps someone. Sorry if I'm not using all the right terminology but let me know if I need to clarify anything. All in all I'm very pleased with the 3575!
