My recommendation is a "Delete all video sources" followed by creating a 
new Video Source, using "Fetch channels from listings grabber" (assuming 
you keep using the HD-PVR or get a CableCARD device--i.e. something 
unscannable), then connecting the new Video Source to your new capture 
card (and it's probably also a good idea to do a "Delete all capture 
cards" and then create new cards, assuming you get some other card 
rather than keep the HD-PVR).

Note that in deleting the old Video Source, any recordings you've 
created previously from DISH will be shown with either incorrect channel 
information or (if there's no channel in the new Video Source with the 
same ID as a previous channel) with just an old channel ID where the 
channel information would be shown in Watch Recordings.  This won't 
cause any problems with MythTV.  If you're concerned that it looks bad, 
you'll be best served moving those old recordings to Video Library, 
which is a better location for storage of large collections of video, so 
is ideal for archival of old recordings.

Also, if you have any "this channel" recording rules, you'll have to fix 
them.  Either delete the old rule (set it to "Do not record this show") 
and then create new rules (where "any channel" rules will always work 
regardless of future channel changes, but if you really think you need 
"this channel" rules, create them with the proper new channels).  
Alternatively, edit the existing rule to change it to an "any channel" 
rule (and, ideally, leave it that way, or if you really think you need 
"this channel" rules, find an episode of the show on the proper channel 
in the guide and edit the rule for it to change it back to a "this 
channel" rule--now on the correct new channel).

If you don't delete the old Video Source--and leave an unconnected Video 
Source in place in the database--you will almost definitely get to a 
point where MythTV just stops working properly (causing it to no longer 
be able to record).  Generally, everything will look fine in the near 
term, but one day, things will just break.  We didn't design MythTV for, 
so we don''t support, disconnected Capture Cards, Video Sources, or 
Channels.
