Folks,

A friend gave me a Iomega DVD+RW drive: hdc: ATAPI 32X DVD-ROM CD-R/RW drive, 
2048kB Cache, UDMA(33) Uniform CD-ROM driver Revision: 3.20 libata version 
1.02 loaded.

This drive works fine in all respects save one. Playing a CD with the smallest 
scratch makes MythTV freeze up.  For instance on one of my CDs at the last 
track, Myth Music always freezes at 2:28.  Other discs freeze at different 
points, but the results are always repeatable. Skipping over the troubling 
spot allows the discs to play on.

Playing a cd in MythMusic drops my memory available from around 463 mB to 
around 400 mB.  

After a Cd stops reading properly sometimes I can move the selector bar around 
and sometimes Mythmusic is completely frozen. If I kill it and go back in and 
try to play a disk the sound is very choppy.   Rebooting X does not resolve 
this, nor does restarting ALSA.  If I reboot the system all is fine till it 
gets to that spot in the disk again.

This also happends when i try to play a disk with Freevo (mplayer), but not 
with kscd (cd player app included with kde).  However, arts is turned off so 
kscd produces no sound.  An alsa buffer issue then?   If so why did it not 
happen with the old drive?

I suspected the cache on the new dvd drive as my Pioneer 104s did not exibit 
this behavior.  However the cache on the Pioneer is only 256k and the cache 
on the new iomega is much larger as i printed above.

Could this new drive just be more sensitive to scratches? If so, why? If that 
is the answer why does this not happen in kscd?

 Any ideas? I called iomega but they were no help (i made the mistake of 
mentioning Linux and they shut me down).

Thanx all,

Bearcat M. Sandor
