I’m not being antagonistic, I’m just pointing out that much of the analysis thus far is unhelpful. You keep stating opinions as absolute facts.
There’s room for one HD channel on a single frequency you identified.
Not considered:
Unused frequencies
Moving remaining 64 QAM multiplexes to 256 QAM
More efficient use of the space that is in use
Lowering the bitrate of some channels.

I am talking about
current configuration as it stands today. As has already been pointed out, VM could do several things to increase capacity e.g. change the remaining 64-QAM multiplexes to 256-QAM. VM didn't change certain ones over, I don't know why, maybe there's some technical reason?? If SP sees this maybe he could explain why these haven't yet been changed over.
They could indeed go the same way as Freeview & Sky and lower the bit rate of existing channels if they wanted to but, as I said earlier, this will have an impact on picture quality.
TSID 101 has a different number of channels in each region, some having more regional variations than others. Northern Ireland also carries RTE and TG4. Again, if SP sees this, maybe he may be able to explain why VM has different transport streams for regional and national channels.
They could certainly use unused frequencies, but VM already had such frequencies available and is actually taking these frequencies and reallocating them to DOCSIS. If there was a pool of unused frequencies, i'm sure VM would be using those for the extra DOCSIS frequencies instead of using these.
What other more efficient use of frequencies do you think that VM could deploy?
As it stands, this is the only remaining space left for an HD channel using the current configuration of a maximum of six on each stream (TSID 23 does have seven, however, but this is due to a BBC timeshare):

It's not a case of people ceasing to post, it's a case of future information now no longer being made available for the forum. This information was never intended for forum use and because of the way that you have conducted yourself, others will lose out on advance information e.g. new channels being added to the service.

The facts that I have posted are verifiable on digitalbitrate and represent the system as it is at this moment in time. The only things which form opinion or speculation is what VM will do to overcome their capacity constraints. There are several things they could do, but only VM staff know what these will be.
There are both polite and rude/antagonistic ways to challenge and, unfortunately for the forum, jfman chose the latter a few days ago to everybody's detriment.
