 Different Versions
 Steam vs Popcap version
Both versions of the game are identical in terms of content. However, the Steam version regularly goes on sale, and also support Steam Cloud natively for the automatic syncing of save game data.
 General Problems
 BASS_ChannelSetAttributes Crash
When starting Plants Vs Zombies (and other PopCap games as well), the game might crash with an error message, BASS_ChannelSetAttributes function not found. This is caused by the game accidentally trying to read a file that shares the name of one of the game files, bass.dll. This happens when there is a file named bass.dll in one of the following folders (I am using C as an example): C:\Windows\, C:\Windows\System32\, or C:\Windows\SysWow64\. Renaming or removing this file will allow the game to run (but may cause problems with the program that installed bass.dll there, keep a backup in case this happens). Bass.dll is usually a library file for sound support created by Un4seen developments and installed with several programs, including many PopCap games. Plants Vs. Zombies uses a different version of the file, and some of the commands have been removed or changed, causing the error.
Another reported fix is running the game in XP compatibility mode. This might introduce other problems, especially on the Steam version.
This problem occurs on both retail and Steam versions of the game.
 Widescreen Support
Plants Vs. Zombies does not support widescreen. Widescreen monitors will typically display "pillarboxing", black bars on the sides of the screen, preserving the 4:3 ratio of the game. Disabling 3D acceleration in the game options may allow stretched widescreen in most computers.
 Steam problems
 Save Game Corruption
Although the game supports Steam Cloud to sync save files the PC and Mac save files are not compatible with each other. Playing the game on one OS and then downloading it and running it on the other will cause the files to be permanently corrupted and you will lose all data. There are also reports of save data suddenly disappearing without clear reason. It is recommended that you make alternative backups of your save data just in case.
