Everything was fine until some risky behaviour got me a worm virus. Oh well a new install of XP was overdue anyway. Now I am trying to get back to before. I installed the KazaaLite codec pack(full), TMPGEnc, VD, PowerDVD5, etc.
I could not play mpeg2's in BSPlayer or SVCD's in PowerDVD5.
I removed PowerDVD5 and re-installed 4 and I can now play SVCD's.
I still cannot play mpeg2's that were encoded by TMPGEnc. I am sure I'll figure out what I'm missing eventually but someone may have the fast answer to fix me up.
