System: MS Windows XP Home Edition Version 2002 Service Pack 3 AMD Athlon 2.6 GHz Processor 4 GB RAM NVidia GeForce 7900 GS (driver updated May 2009) Windows Media Player Hello, I've seen some posts with the following similar problem but have yet to find a solution: Choppy/slow video playback and very slow sound when I try to play (some, not all) mpeg files recorded with my (Sinovideo) DVBT player. Frustrated that some files play OK while others do not (and some files that used to play OK now don't). As I am willing to try anything ...any advice at all would be great (even if it's just to point me in the right direction to get advice). Cheers, :-(

micstrix, 'fraid I can't offer you more than a SWAG. Generally, choppy sound indicates buffering which occurs with a shortage of memory. 4GB should be plenty UNLESS it's already claimed. Could it be that you need to clear 'index.dat'? A common ailment is a file called 'index.dat'. It gets read every time and can take quite a while if it’s too bloated (Choppy video?). It's like a log file and keeps a record of every site you visit on the web. Empty, it's 32K, but it can grow HUGE. It's a protected file and can't be deleted by normal methods. CCleaner (free @: http://www.ccleaner.com/) can get rid of it (not to worry, it gets rebuilt EMPTY on the next boot.). HTH. Ed in Texas.

Hi Ed, Thanks for the prompt reply. I've already tried deleting index.dat. I've "baby sitted" this thing with ccleaner, avg, spywareblaster, spywaredoctor, avast, ad-aware, advanced system care... I've also tried a number of things including complete system reinstallation (ouch). I've given up on my DVBT dongle "thingy" and have had enough of video editing on Windows, which was never a stable OS. I'll give Windows one more shot with a top of the range graphics card before moving to Unix. Once again, thanks for the response. Regards, micstrix
