I was able to reinstall MLBMC in Kodi, and it seems to work OK. It’s somewhat convoluted to do. divingmule has stopped maintaining the add-on and another volunteer, Youioup, has been working on it. Since the add-on is not in the official repository any longer, you must install it another way.
The MLBMC thread at kodi.tv:
Youioup’s github for the add-on:
When you download the release (the ‘download’ button on the right of the Github page), you’ll need to locate a zip file inside the zip file you download called ‘plugin.video.mlbmc.2.0.75.zip’. the numeric string may differ; it’s the release number. That’s the install-ready zip that Kodi needs to see to install the add-on.
I followed these instructions to upload the zip file to Kodi / XMBC’s ‘Home’ directory on the Seas0npass/Firecore JB 5.3 ATV2:
The article was posted in 2012 and uses screenshots taken with a much older version of XBMC. The basic procedure: Copy the zip file to Kodi’s Home Folder as described using SFTP. Navigate to “Settings > Add-Ons > Install from zip file”. When the file source dialog displays open the ‘Home Folder’. I am not sure if it’s labeled ‘Home Folder’ or ‘Home’. Once you’ve selected it, you should see the filename of the zip file you uploaded earlier along with some other info and folders. Select it and Kodi will install the add-on.
You’ll need to configure it with your MLB.tv account info. My install went without a hitch and I have not had problems with playback or logging in or anything. Your experience may vary; posting to the MLBMC thread at kodi.tv for help and with questions is your best bet if you run into problems.
A note to consider: I found that I had to restore and jailbreak the ATV a couple of times. The first time the restore-to-current went fine but then performing the JB failed as the device became stuck in DFU mode. I was able to restore it again and the second time everything went smoothly. However, other users here have sometimes reported that getting stuck in DFU mode can make the device unrestorable. I also had to pay for the Firecore software again, which was aggravating, but does provide access to what must be considered the final release of the software, including an implementation of Infuse which provides excellent downconversion of 1080p content to the ATV2’s 720p.
Finally, in January, the development lead for the Apple TV 2 implementation of Kodi announced that the current release is the final release for the platform:
As absurd as it seems to relegate these less-than-ten-year-old devices to history, that is the reality we are facing. Given that MLB.tv is the subject of active and well-executed technical development and that MLBMC is both not an official MLB licensee nor officially supported under Kodi, one must anticipate the eventual loss of MLB.tv playback functionality on these jailbroken devices at any time.
Hope this helps.
