Replay bugs, possible fixes, how to deal with them, possible causes...

[ScarfaceCrow]

Hi folks, I'm creating this tread to find a solution to broken Replays on TF2, yesterday I was recording some frags for my "goomba stomp frag movie", so basicly playing on Manntread friendly maps (aka Hightower, nucleos etc...) with replays enabled, when I was at Frontier I pulled a Pogoing jump in the "middle long ramp" of the map and bang, crushed a Pyro followed by a triple critical rocket kill, downloaded the replay, and for my surprise, when try to load the replay or .dem from it I have an engine crash (CModelLoader::FindModel: NULL), is that an internal error related with the game ? or is caused by the use of 3rd part content aka GameBanana skins (I have some HD skins, NassimO & Blaholtzen's pack), I heard about people with the game Unable to find some models as an error, also in my research I found people with L4D2 custom maps and Gary's Mod uses having this very same error.

So, I didn't gave up of my quest, and started to mess with the game files, took some backup copies and open them in the wordpad, and discovered that the .dmx have some data about the replays, like who you killed, who killed you, by this I managed to find the servers Ip, and the servers FTP where all the demos are stored, and downloaded the whole game that I played, the problem is, they are in a .block files, after some research I discovered that this ones are compressed 15 second session of ticks of all players, so, is there a way to compile those into .dem ? I heard that bzip2 is used in the process of compressing if that helps.

Also I find in this video, with an solution that the author claims to fix most of the problems related to Replays, posting it here to see if help you guys (use it at your own risk).

1.Open the registry (start, run, then write: regedit, then press enter).
2.Go to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] and change the value of SessionPoolSize to 20 hexadecimal / 32 decimal. For 64-bit users: 40 hexadecimal / 64 decimal.
3. Make sure you have quicktime installed correctly
4. Reboot windows and start the game.
