Group,
I have been running Myth 0.18.1 for about 2 months now, and all was well up until about 3-4 weeks ago when I started have trouble playing back recordings. Two things are happening, but I cannot tell
if they are related.
1. After about 4 minutes into a show the fastforward stops working. It just jumps ahead one second. The display also changes from "Skip Ahead \n 1:00 of 57:00" to "skip Ahead \n 0:06:15 of 1:25:37"
I don't understand why it doesn't understand the length of the show.
2. Periodically I get a jitter in the video. These appear to correlated with the following messages in the frontend log.
[mpeg2video @ 0xc24810]warning: first frame is no keyframe
[mpeg2video @ 0xc24810]ac-tex damaged at 33 14

It looks to me like I have a buffering problems, but I don't have a clue where to start. I know the problem is in the front end. If I copy the NVU files to my PC and play them as WMV's they play
just fine.
I was monkey-ing around with the commercial skip and writing files to a DVD about the time that this problem started. Unfortunately I did a poor job of documenting what changes I made and what
effect they had.
I have considered doing a dump of the settings table from a fresh install and compare the differences.
Machine Info:
Shuttle B81
P4 2.8GHz
1Gb Ram
128G SATA HD
Haupaugge PVR-150
Runs both the Frontend and Backend
It runs with very low load
Any thoughts or direction would be greatly appreciated.
Thank You,
Brandon Saunders
