I live in Adelaide, Australia and I use Media Portal for my TV viewing and recording needs and Meedio for the rest of my media needs (NOT MCE)...
Media Portal has the ability to run comskip on files and skip ads on playback automatically, but does not compress or cut the ads from the recorded file, just produce a chapter file. I have found this to work for me about 90% effective. Comskip works brilliantly, but I don't think MCE is capable of auto-skipping ads like Media Portal. Have you even tried downloading Comskip itself, configuring and running it against one of your recordings? There is also a brother to comskip called comclean that can take a processed comskip file and cut the ads out just like MCEBuddy tries to do.
For editing out commercials the manual way, VirtuaDub is one of the FREE and best ways of doing so. You can easily seek through to find the scene changes and then just add marks to cut out sections and then output the final product with your choosing of audio and video encoders (that you have installed).
I have a lot of respect for the guys who create these applications, bugs or not. Though it may not actually work for me, the fact is that they offer it FREE and if it doesn't work for me all I have lost is a bit of time. Anyone who recons that they can create something better is welcome to forward their efforts to the HTPC community.
Not quite sure where you were headed with your post there tamxir. I have been quite a hardcore HTPC enthusiest for the past 2 years. I have a dedicated HTPC with touchscreen, run a large amount of applications and scripting on my XP HTPC machine and have a central media server for my media. I have never had a performance issue, crasy, lockup... anything except what I built the machine for. It has been rock solid and there have only been a couple of things that don't work, such as MCEBuddy not actually cutting my ads. It does compress my files so it still saves me disk space and I can edit the ads out myself after if I want in 5 minutes.
