I'm amazed you bother keeping track of that kind of thing =)

Could be a difference in the software on the cablebox itself as well?

some fixes for how firewire recordings are handled, the inclusion of a
firewire signal monitor, tracking boxes by GUID instead of port/node
(great if you have multiple boxes connected to the same computer), etc
Most of the changes were part of ticket
http://svn.mythtv.org/trac/ticket/1648 from what I understand.

My problem is, mine will be short anywhere from 5seconds to 5
minutes!(never too long) Usually closer to 5-10 seconds, with
noticeable interruptions in the datastream for longer incorrect times.
It gets worse during Prime Time, even if I'm only recording one show
at the given time, as well some channels (frequencies) are worse than
others on those days.

I'd love HDNet for MLS games, other than that I don't really know what
I'm missing. InHD has this new Mojo thing, which actually has some
decent shows (Beer Nutz, London Live).
