I upgraded to MC21 today specifically for the new TV features and to test if it might replace Windows Media Center. Setup is a PITA, at least, compared to WMC. It took me awhile to get MC21 to recognize my HDHomeRun Prime tuners. Now I'd like to see if MC21 can organize my TV channels as easily as WMC.
I have a total of 5 tuners - 3 with the HDHomeRun Prime and these are all CableCARD tuners and my cable provider is Charter Communications. Luckily, all of the channels are 'copy freely'. The other 2 tuners are from my HDHomeRun Dual ATSC tuner and are connected to an antenna in my attic. These are providing local OTA broadcasting and are listed as 'Digital Antenna' tuners.
Originally when I configured TV for WMC and my HDHomeRuns, I ran the HDHomeRun Install Wizard. The channel scan for CableCARD finds 276 programs. The channel numbers range is from 2 to 997. The channel scan for Digital Antenna finds 23 channels. The guide numbers range is from 3.1 to 57.3.
Between the CableCARD and Digital Antenna tuners, I end up with a lot of channels we don't need/watch and some redundancy.
The Digital Antenna channels include the local affiliates of the major networks like ABC, NBC, CBS, and FOX. These are all in HD. They also provide a bunch of subchannels. The NBC affiliate here is WMTV and they have it listed as WMTV-HD on guide channel 15.1, but it is listed as CH19-3 for the tuner.
For cable TV Charter provides both SD and HD versions of many channels. The SD cable channel for NBC uses the tuning and guide number 5 and it is called WMTV-NB (I think that is short for WMTV-NBC and the C is just getting cut off). The HD cable channel for NBC is on 615 for both tune and guide number and is listed as WMTV DT.
This means we can have 3 different versions of NBC - the HD version from both cable (WMTV DT) and OTA (WMTV HD) and the SD (WMTV-NB) version from cable.
WMTV/NBC was on channel 15 way back when all our TV was OTA analog. In the 70s when cable arrived, WMTV/NBC was on cable channel 5. Since we've been subscribing to cable for such a long time, we've gotten used to it being on channel 5. However, now that we get the HD version, we never watch the SD version of WMTV/NBC. Thankfully, Windows Media Center is pretty flexible with how you assign or map channel numbers. I can map or swap channels 5 and 615 so when my family wants to watch channel 5, the HD version of WMTV/NBC plays. Since I swapped 5 and 615, 615 is now the SD version and I have that channel turned off in the WMC TV Guide, so it doesn't appear on the guide. I can also group channels together so a single channel can have multiple sources. In this case I grouped the cable HD channel of WMTV/NBC - WMTV DT with the Digital Antenna channel of WMTV/NBC - WMTV HD. So with the 5 tuners (3 CableCARD and 2 Digital Antenna) I can map five different sources to channel 5. With Windows Media Center they all share the same guide data so program descriptions are always in sync. Pick channel 5 from the guide or with the MCE remote and you watch the HD version of WMTV/NBC. 5 people using different HTPCs can watch these 'network' HD channels simultaneously.
This makes the guide fairly easy to use. All of the familiar channels/stations are assigned to the familiar cable channel numbers. Every possible HD version of the channel is played and the SD versions are ignored/hidden. For those channels that are only available on cable, like ESPN, the SD channel 24 was swapped with the HD channel 660. Again, when picking channel 24 with the remote ESPNHD plays. Since these are only available on cable the only sources for ESPNHD are the three CableCARD tuners. So only 3 people using different HTPCs can watch cable only channels simultaneously.
I have a few question about doing this in MC21. I hope it is possible.
Is there a way to remap channels?
Can you combine channels that use the same program information to a single channel?
I haven't been able to find anything about doing this in any of the television threads. If this is explained somewhere, I'd really appreciate a link to the instructions. Any help is greatly appreciated.
