Thanks so much for your help, guys. Unfortunately, do to the lack of hardware encoding for the analog portion, I'm going to have to skip the fusionhdtv5.
Instead, for now, I'm going all-analog (snickers). Thinking of either the WinTV PVR 150 or Visiontek Xtasy theater 550 pro (leaning toward the 550 due to its fm tuner, and higher-quality ntsc tuner, although it does lack a remote...).
In the future, when I get some more extra money, or I get a nice deal on a fusion, I'll definitely get one in addition to my analog card. Then I'll have (hopefully this'll all work nicely in Mediaportal)
an HDTV tuner (fusion) for viewing and recording
an analog tuner (one of the two listed above) for viewing and recording analog
an existing TV Wonder (yes, it's crappy, but...) solely for viewing analog
and the analog tuner in the fusion solely for viewing analog
wow, that's a lot. hopefully it'll all work.
Thanks again, guys, for all your help. The FusionHDTV5 looks great for hdtv, and I'll definitely be getting it soon, but for now, my main concern is the PVR-like functions that I can use with my cable through a hardware encoder.
P.S.: anybody know if the quality of the ntsc tuners in the wintv pvr 150 and the visiontek xtasy 550 pro are fairly similar? If they are, then I'll have to weigh the remote versus fm tuner areas...oh, decisions, decisions.
