Is this some bastardized version of HD?

<br>up to about 8 channels into the frequency for one channel and then<br>remaps the numbers so 100.1 becomes 557, 100.2 becomes 530, 100.3<br>becomes 623, etc.</blockquote><div><br>That's good to know. We're veering off topic a bit, but has anybody tuned into any OTA HD channels at these freqs? I get access to some On Demand stuff at
113.0 to 113.2 as well as a couple Music Choice channels, but that's it.<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">> Anyways, since my TV doesn't tune that high, I was wondering if I

<br>to 324 and MythTV would scan for TV on the additional EIA-542 channels.<br>If a cable operator went very much past 2000 Mhz they would need more<br>expensive cabling and equipment so this is unlikely, they would just<br>
switch to the cheaper fiber to the home at that point.</blockquote><div><br>I'm going to flag this email in the hopes that it will make more sense as I learn more :-) . Thanks for the wealth of information.</div><br>
