[Extractstream [MM]] video stops half way thru my mpeg

[u2cjfs0fp02@sneakemail.com]

i used tmpegc to encode my audio video streams. i got the streams using tivoapp. now every mpeg i encode the video stops about 20 mins into it. the sound continues however till the end. when i just mux my audio video files it works perfictly but when i encode them to another format such as vcd or custom it does this.
