Thanks.

debug gives the message "ProgDVBEngine - Create filter error (Video decoder)"
2 recordings then play with audio only, the third has video and audio
Stopping gives the message "except - ProgDVBEngine::Playback_Play"

With normal starting, the program doesn't get as far as showing the slider ...

I'll get a bigger disk when I've got a proven system.
Please note that my problem is with playing recordings, not making them.
The recordings are fine and will play in MPC-HC, DVB Dream, TotalMedia 3, VLC ...

Sorry, don't know what "split file settings"means.
Thanks, amac.

I am unable to play back long recorded files on ProgDVB.
"Long means about 70 mins. 40 min ones are OK.
They will play on, eg, Media Player Classic (and others).
The longer files cause a system lockup - need Ctrl-Alt-Del to get out.

ProgDVB 6.48.4Std (but earlier versions also had this problem).
XP ...
