Hacking How is video playback on Vwii?

ISFShax + Decaffeinator recovery help: vWii won't boot, vWii NAND Restorer "Error determining NAND type", Wii U now 160-0101

Hi everyone, I'm looking for help from someone experienced with ISFShax, Decaffeinator, and vWii recovery. I've reached a point where I'm not comfortable trying anything else without advice. System setup: Wii U (USA) ISFShax installed Tiramisu/Aroma installed Full NAND OG backup Backup files: otp.bin seeprom.bin slc.bin slccmpt.bin What happened: I was working on my vWii while setting up WiiLink. After making those changes, the vWii stopped booting. Selecting "Wii Menu" from the Wii U Menu shows a black screen for a few seconds before returning to the Wii U Menu. Priiloader is no longer accessible. What I've already tried: Ran vWii Decaffeinator. Initially it failed because FTPiiU was enabled. After disabling FTPiiU, Decaffeinator launched normally. My usual recovery method is: Run Decaffeinator. Let it remove the required files. Boot into Wii U System Settings. Remove the SD card. Perform a Wii U system update to reinstall the missing vWii titles. Unfortunately, that workflow is now broken due to a 160-0101 error being thrown at me if I attempt to access the default WiiU meny (which has forced me to boot around it into tiramisu) I also tried vWii NAND Restorer (the Wii U application), using my original slccmpt.bin and matching otp.bin from this same console. The files are in the correct location, but the application always reports: Error determining NAND type After the Decaffeinator attempt, the Wii U now throws: 160-0101 ISFShax is still functioning/installed, but not aware of any button combos I can access. My questions: What causes vWii NAND Restorer to report "Error determining NAND type" when using a valid backup from the same console? Is there a recommended recovery procedure using ISFShax for this situation? Should I be restoring only slccmpt.bin, or is there another recovery method I should be using instead? Is there a way to force the Wii U to reinstall the required vWii titles if the normal Decaffeinator update workflow can no longer be completed? I'm trying to avoid making the situation worse, so I haven't continued experimenting beyond this point. Any help would be greatly appreciated. Thank you.

I remember watching movies a long time ago on my Wii (I think it was called MPlayer), and if I skipped too fast, the app would crash.

Is this fixed on the Wii U? Can I stream something from a local network (I know this has existed for sometime) or will the same thing happen?

for Wii/vWii you can use WiiMC and setup a smb share for streaming
Setting up smb for WiiMC
or
for Wii U you can setup a plex media server on your pc and use the Wii U Internet browser to watch
