I read everything and I'm a techno junkie (senior IT technician) so please remove the 14-yo comment.
The issue there is that I followed the instructions in the book included with my 8300HD. Mind you it's in french version and custom written by Videotron. I never saw any "closing" step to confirm the code and the various remote guides I read in the SA ExplorerClub part doesn't tell this as well. That's why I'm asking... If you see this when I don't see, please indicate where
However, one thing of interest : The code I got for this remote and TV is 222 when in the SA guides, all i see is 4 digit codes ??? This may explain why it didn't work well.
To make sure I did correctly, here's the steps as outlined in the guides :
1- Press and hold Select + TV buttons till the TV button light up.
2- Enter the code and if the code is valid, the TV will power off. This happened when I entered 222.
3- I pressed Power to power on the TV.
4- Toyed with the various buttons to make sure it works. It does work correctly.
5-___________________ (This may be what's missing but i don't think it's needed). Something tell me to hit CH+ to confirm but it's unclear. I already used this to change channels to make sure so it obviously saved the code if it is the case.
As soon as i press CBL then back to TV, it doesn't work so I must reprogram again to make it work. For the remote model, it's home and I'm at work so I'll post this when I get back home but it's the one included with the 8300HD from Videotron (silver with black backside).
