I do miss the flexibilities of CC.
@Jean0987654321 reminded me, OTA is still best option for local channels if you can physically get them with an HDHR tuner. 3.0 is fools gold at this point, focus on what you can get with 1.0 tuner. If you aren't able to get OTA or want more than just what OTA offers (assuming yes since you mentioned CC access previously), then the other options are get a subscription to one of the streaming services and use one or more of the following:
TVE = Diminishing flexibility. Still the easiest and a decent option to get certain content (ABC, CBS, ESPN, Fox Sports, etc), but lot of channels no longer available.
Chrome Capture = Works for some. Seems to be sensitive to Chrome updates on the machine acting as the server. Also requires a decent amount of horsepower in your machine to run more than 1 "stream".
ESP+ = Was great at one time for sports, but ESPN has basically DRM all the non-linear content. Still good to get linear ESPN content, but you can get that via TVE, so unless you are using for one of the other sources it provides for (works well with NFL Sunday ticket as an example).
ahc = I've not been successful with this. Seems to have a steeper learning curve that other solutions, but that may just be me. Requires an hdmi encoder and a streaming stick(s) (fire, ONN).
ADBTuner = My "supplemental" solution. I use this with ONN streaming sticks and use this to backfill those channels I want that done't come in through TVE. Also requirees encoder and streaming stick(s).
There's also Fubo Project which used to be awesome when combined with TVE, but several major channels have been DRMed and has reduced the value.
Others can provide additional context and their perspective which may be different than mine. That's the beauty of CDVR, you have several pathways to pursue.
